gridwxcomp - Grid Weather Station Comparison¶

A package for comparing climate station time series data to gridMET (or other gridded) data. Major functionality includes tools to:

pair station locations with overlapping grid cells
download gridMET data from OpenDap server
calculate mean bias ratios between station and gridded data and other statistics
spatial interpolation of bias ratios with multiple interpolation options
build geo-referenced files of point data and interpolated rasters
extract zonal means for a subset of gridcells
graphics, e.g. time series comparisons and interpolated residuals at stations
tools for doing the same analysis with arbitrary gridded and point data

Bias ratios calculated by gridwxcomp can be used to correct bias of grid to station data based on the properties of the stations. For example, monthly humidity ratios between station and grid for stations within agricultural settings can be used to estimate grid bias relative to agricultural locations. gridwxcomp includes an intuitive command line interface and a Python API.
