Description
A follow-up PR for geostationary sampler of part-1 (#2528), coauthored with @tclune and @bena-nasa.
The transformation function is added to convert in between ABI_XY grid (GOES-R series) and geodetic lon/lat grid. The keyword to turn on the geostationary output is
GRIDNAME: ABI_Fixed_Grid
.Worth noting that
i) the previous function to read in 2D lat-lon grid is untouched.
ii) an optional variable thin_factor is available to reduce the obs grid resolution for debug runs
iii) added if (has_mask) dstMaskValues = [MAPL_MASK_OUT] from @tclune's comment on PR part-1
iv) avoided the global 2D variables for arr_lon/arr_lat, because a global 1D variable (X and Y) on shared memory is sufficient to generate ABI_XY grid (ndim=5424) due to analytic function for transformation
Input:
Output is the same as the part-1 PR, posted again:
The previous lat-lon XY grid input for 2D variables in netCDF is changed to
