gridwxcomp - Grid Weather Station Comparison¶
A package for comparing weather station data to gridded weather data that are hosted on Google Earth Engine. Major functionality includes:
parsing of multiple weather stations and weather variables and metadata
downloading point data from gridded datasets on Google Earth Engine at weather station locations
temporal pairing of station and gridded data
unit handling and automated conversions
calculation of mean bias ratios between station and gridded data and related statistics
performing spatial mapping and interpolation of bias ratios with multiple options
calculation of residuals between spatially interpolated bias ratios and those computed at station locations
building geo-referenced vector and raster data of spatially interpolated and point data
zonal averaging of spatially interpolated bias results using a fishnet grid
interactive graphics (time series, scatter, and bar charts) comparing station and gridded 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.
