6 Agroclimate Rasters
This chapter will show how to
- take a raster time series of observed (or modeled) weather data
- Spatial CIMIS
- gridMet
- PRISM
Convert it to stars (see caladaptr vignette)
Use
stars::sapply()
to compute agroclimate metrics pixel-by-pixel- key thing is to put the computation in a function that takes a timeseries vector and spits out the agroclimate metric
Example: Compute the number of days > 105 degF for one growing season (Apr - Sep) for a small county
- Visualize multi-year agroclimate metric rasters with animation, or a slideshow kind of thing
