aospy.Region
no longer can be instantiated usinglat_bounds
andlon_bounds
keywords. These have been replaced with the more expliciteast_bound
,west_bound
,south_bound
, andnorth_bound
(266
). By Spencer Hill.- Drop support for Python 2.7 and 3.4, since our core upstream dependency xarray is also dropping these soon (
255
,280
). By Spencer Hill. - Deprecate
Constant
class andconstants.py
module. Physical constants used internally by aospy are now stored in_constants.py
(fixes50
via223
). By Micah Kim. - Deprecate
Units
class, so now theunits
attribute of theVar
class is a string. (fixes50
via222
). By Micah Kim. - Deprecate
CalcInterface
class. Now, to instantiate aCalc
object, pass it directly the parameters that previously would have been passed toCalcInterface
(fixes249
via250
). By Spencer Hill. - Deprecate
utils.times.convert_scalar_to_indexable_coord
, since as of xarray version 0.10.3 release, the functionality is no longer necessary (fixes268
via269
. By Spencer Hill.
- Corrected link to documentation badge on repository main page (
213
). By DaCoEx.
- Use an
xarray.CFTimeIndex
for dates from non-standard calendars and outside the Timestamp-valid range. This eliminates the need for the prior workaround, which shifted dates to within the range 1678 to 2262 prior to indexing (closes98
via273
). By Spencer Clark. - Create
utils.longitude
module andLongitude
class for representing and comparing longitudes. Used internally byaospy.Region
to construct masks, but could also be useful for users outside the standard aospy workflow (266
). By Spencer Hill. - Add support for
Region
methodsmask_var
,ts
,av
, andstd
for data that doesn't conform to aospy naming conventions, making these methods now useful in more interactive contexts in addition to within the standard main script-based work flow (266
). By Spencer Hill. - Raise an exception with an informative message if
submit_mult_calcs
(and thus the main script) generates zero calculations, which can happen if one of the parameters is accidentally set to an empty list (closes253
via254
). By Spencer Hill. - Suppress warnings from xarray when loading data whose dates extend outside the range supported by the numpy.datetime64 datatype. aospy has its own logic to deal with these cases (closes
221
via239
). By Spencer Hill. - Add units and description from
Var
objects to output netcdf files (closes201
via232
). By Micah Kim. - Remove potentially confusing attributes from example netcdf files. (closes
214
via216
). By Micah Kim. - Cleanup logic for Dataset drop on dimensions with and without coords. Use Dataset isel instead. (closes
142
via241
). By Micah Kim. - Expose
data_vars
andcoords
options toxr.open_mfdataset
in DataLoaders. These options control how variables and coordinates are concatenated when loaded in from multiple files; by defaultaospy
usesdata_vars='minimal'
andcoords='minimal'
, but there could be use cases where other options are desired. See the xarray documentation for more information (closes236
via240
). By Spencer Clark. - Allow for variables to be functions of other computed variables (closes
3
via263
). By Spencer Clark.
- Use the new
Longitude
class to support any longitude numbering convention (e.g. -180 to 180, 0 to 360, or any other) for both definingRegion
objects and for input data to be masked. Fixes bug wherein a region could be silently partially clipped off when masking input data with longitudes of a different numbering convention. Fixes229
via266
. By Spencer Hill. - Cast input DataArrays with datatype
np.float32
tonp.float64
as a workaround for incorrectly computed means on float32 arrays in bottleneck (see pydata/xarray#1346). If one would like to disable this behavior (i.e. restore the original behavior before this fix), one can set theupcast_float32
keyword argument in their DataLoaders toFalse
. Fixes217
via218
. By Spencer Clark. - Switch from using
scipy
tonetcdf4
as the engine when writing to netCDF files to avoid bugs when usinglibnetcdf
version 4.5.0 (235
). By Spencer Hill. CalcSuite
(and thussubmit_mult_calc
) now skips calculations that involve time reductions of non-time-defined variables.Calc
now raises a ValueError when instantiated with a non-time-defined variable but has one or more time-defined reductions. (closes202
via242
). By Micah Kim.
- Create Travis CI environment that tests against the xarray development branch. (closes
224
via :pull: 226). By Micah Kim. - Use
nbconvert
andnbformat
rather thanrunipy
to test the tutorial Jupyter notebook, asrunipy
is deprecated (239
). By Spencer Hill. - Add flake8 to Travis CI environment to check that new code adheres to pep8 style. Add verbose flag to pytest test suite. (closes
234
via237
). By Micah Kim.
aospy
now requires a minimum version ofdistributed
of 1.17.1 (fixes210
via211
).aospy
now requires a minimum version ofxarray
of 0.10.6. See discussion in199
,240
,268
,269
,273
, and275
for more details.
This release includes some new features plus several bugfixes. The bugfixes include some that previously made using aospy on pressure-interpolated data very problematic. We have also improved support for reading in data from the WRF and CAM atmospheric models.
As of this release, aospy has at least 2(!) confirmed regular users that aren't the original aospy developers, bringing the worldwide total of users up to at least 4. The first user-generated Github Issues have now also been created. We're a real thing!
- Use
dask.bag
coupled withdask.distributed
rather thanmultiprocess
to parallelize computations (closes169
via172
). This enables the optional use of an externaldistributed.Client
to leverage computational resources across multiple nodes of a cluster. By Spencer Clark. - Improve support for WRF and NCAR CAM model data by adding the internal names they use for grid attributes to aospy's lists of potential names to search for. By Spencer Hill.
- Allow a user to specify a custom preprocessing function in all DataLoaders to prepare data for processing with aospy. This could be used, for example, to add a CF-compliant units attribute to the time coordinate if it is not present in a set of files. Addresses
177
via180
. By Spencer Clark. - Remove
dask.async
import inmodel.py
; no longer needed, and also prevents warning message from dask regarding location ofget_sync
function (195
). By Spencer Hill.
multiprocess
is no longer required for submittingaospy
calculations in parallel (see discussion in169
and pull request172
).aospy
now requires an installation ofdask
with version greater than or equal to 0.14 (see discussion in pull request172
).
- Remove faulty logic for calculations with data coming from multiple runs. Eventually this feature will be properly implemented (fixes
117
via178
). By Spencer Hill. - Only run tests that require optional dependencies if those dependencies are actually installed (fixes
167
via176
). By Spencer Hill. - Remove obsolete
operator.py
module (fixes174
via175
). By Spencer Clark. - Fix workaround for dates with years less than 1678 to support units attributes with a reference date years not equal to 0001 (fixes
188
via189
). By Spencer Clark. - Fix bug which would prevent users from analyzing a subset within the Timestamp-valid range from a dataset which included data from outside the Timestamp-valid range (fixed in
189
). By Spencer Clark. - Toggle the
mask_and_scale
option toTrue
when reading in netCDF files to enable missing values encoded as floats to be converted to NaN's (fixes190
via192
). By Spencer Clark. - Force regional calculations to mask gridcell weights where the loaded datapoints were invalid instead of just masking points outside the desired region (fixes
190
via192
). By Spencer Clark. - Retain original input data's mask during gridpoint-by-gridpoint temporal averages (fixes
193
via196
). By Spencer Hill. - Always write output to a tar file in serial to prevent empty header file errors (fixes
75
via197
). By Spencer Clark. - Allow
aospy
to use grid attributes that are only defined inRun
objects. Previously if a grid attribute were defined only in aRun
object and not also in the Run's correspondingModel
, an error would be raised (fixes187
via199
). By Spencer Clark. - When input data for a calculation has a time bounds array, overwrite its time array with the average of the start and end times for each timestep. Prevents bug wherein time arrays equal to either the start or end bounds get mistakenly grouped into the wrong time interval, i.e. the wrong month or year (fixes :issue 185 via
200
). By Spencer Hill.
This release improves the process of submitting multiple calculations for automatic execution. The user interface, documentation, internal logic, and packaging all received upgrades and/or bugfixes.
We also now have a mailing list. Join it to follow and/or post your own usage questions, bug reports, suggestions, etc.
- Include an example library of aospy objects that works out-of-the-box with the provided example main script (
155
). By Spencer Clark and Spencer Hill. - Improve
examples
page of the documentation by using this new example object library (164
). By Spencer Hill. - Improve readability/usability of the included example script
aospy_main.py
for submitting aospy calculations by moving all internal logic into newautomate.py
module (155
). By Spencer Clark and Spencer Hill. - Enable user to specify whether or not to write output to .tar files (in addition to the standard output). Also document an error that occurs when writing output to .tar files for sufficiently old versions of tar (including the version that ships standard on MacOS), and print a warning when errors are caught during the 'tar' call (
160
). By Spencer Hill.
- Update packaging specifications such that the example main script and tutorial notebook actually ship with aospy as intended (fixes
149
via161
). By Spencer Hill. - Use the 'scipy' engine for the xarray.DataArray.to_netcdf call when writing aospy calculation outputs to disk to prevent a bug when trying to re-write to an existing netCDF file (fixes
157
via160
). By Spencer Hill.
This release includes fixes for a number of bugs mistakenly introduced in the refactoring of the variable loading step of calc.py
(90
), as well as support for xarray version 0.9.1.
- Support for xarray version 0.9.1 and require it or a later xarray version. By Spencer Clark and Spencer Hill.
- Better support for variable names relating to "bounds" dimension of input data files. "bnds", "bounds", and "nv" now all supported (
140
). By Spencer Hill. - When coercing dims of input data to aospy's internal names, for scalars change only the name; for non-scalars change the name, force them to have a coord, and copy over their attrs (
140
). By Spencer Hill.
- Fix bug involving loading data that has dims that lack coords (which is possible as of xarray v0.9.0). By Spencer Hill.
- Fix an instance where the name for pressure half levels was mistakenly replaced with the name for the pressure full levels (
126
). By Spencer Clark. - Prevent workaround for dates outside the
pd.Timestamp
valid range from being applied to dates within thepd.Timestamp
valid range (128
). By Spencer Clark. - Ensure that all DataArrays associated with :py
aospy.Var
objects have a time weights coordinate with CF-compliant time units. This allows them to be cast as the typenp.timedelta64
, and be safely converted to have units of days before taking time-weighted averages (128
). By Spencer Clark. - Fix a bug where the time weights were not subset in time prior to taking a time weighted average; this caused computed seasonal averages to be too small. To prevent this from failing silently again, we now raise a
ValueError
if the time coordinate of the time weights is not identical to the time coordinate of the array associated with the :pyaospy.Var
(128
). By Spencer Clark. - Enable calculations to be completed using data saved as a single time-slice on disk (fixes
132
through135
). By Spencer Clark. - Fix bug where workaround for dates outside the
pd.Timestamp
valid range caused a mismatch between the data loaded and the data requested (fixes138
through139
). By Spencer Clark.
