Release v0.73.0 · holukas/diive

v0.73.0 | 17 Apr 2024

Added new function trim_frame that allows to trim the start and end of a dataframe based on available records of a
variable (diive.core.dfun.frames.trim_frame)
Added new option to export borderless
heatmaps (diive.core.plotting.heatmap_base.HeatmapBase.export_borderless_heatmap)

Added more info in comments of class WindRotation2D (diive.pkgs.echires.windrotation.WindRotation2D)
Added example data for EddyPro full_output
files (diive.configs.exampledata.load_exampledata_eddypro_full_output_CSV_30MIN)
Added code in an attempt to harmonize frequency detection from data: in class DetectFrequency the detected
frequency strings are now converted from Timedelta (pandas) to offset (pandas) to .freqstr. This will yield
the frequency string as seen by (the current version of) pandas. The idea is to harmonize between different
representations e.g. T or min for minutes. Currently it seems that pandas is not consistent with e.g. the
represenation of minutes, using T in .infer_freq() but min
for Timedelta (
see here). (diive.core.times.times.DetectFrequency)

Updated class DataFileReader to comply with new pandas kwargs when
using .read_csv() (diive.core.io.filereader.DataFileReader._parse_file)
Environment: updated pandas to v2.2.2 and pyarrow to v15.0.2
Updated date offsets in config filetypes to be compliant with pandas version 2.2+ (
see here and here), e.g., 30T was changed
to 30min. This seems to work without raising a warning, however, if frequency is inferred from available data,
the resulting frequency string shows e.g. 30T, i.e. still showing T for minutes instead
of min. (diive/configs/filetypes)
Changed variable names in WindRotation2D to be in line with the variable names given in the paper by Wilczak et
al. (2001) https://doi.org/10.1023/A:1018966204465

Removed function timedelta_to_string because this can be done with pandas to_offset().freqstr
Removed function generate_freq_str (unused)

Added test case for reading EddyPro full_output
files (tests.test_loaddata.TestLoadFiletypes.test_load_exampledata_eddypro_full_output_CSV_30MIN)
Updated test for frequency detection (tests.test_timestamps.TestTime.test_detect_freq)
