Update GEE script to calculate sum in addition to max for each vegetation index for the growing season

Run time series model in R at site level for four test sites.

Obtain peak yield data from UC Reserve sites across CA and compare to NDVI, EVI, NIRv. Create 'modeled' peak productivity from relationships and use that instead of vegetation indices in analyses?

Reach out to Jones et al about access to annual rangelands file used in their app.

I tried running the GEE script, but the vizParams object isn't defined in the script. Can you add that code?

Calculate CV across time series, by pixel.

Incorporate masking of pixels to < 25% Tree Canopy Cover in GEE script (currently in R script)

Use FVEG in GEE to mask vegetation indices to annual grassland pixels.

Look into SSURGO 'ecological sites'. Consider using for delineating areas that are similar based on substrate and climate, instead of RMZs. Identify and create asset for use in GEE.

Re-write GEE script that calculates veg indices to loop over ImageCollection, rather than have to cut and paste for different years.

Plot test site-level CV by precipitation. How to aggregate precipitation? CV? Mean? Max?

Add water mask to GEE script

When I execute line 21 of the 'new plotting script' file I get the following error:

`

net <- graph.data.frame(links, nodes, directed=T)
Error in graph.data.frame(links, nodes, directed = T) :
Some vertex names in edge list are not listed in vertex data frame
`

I can't seem to generate the net data structure using this code to run through the network mapping functions.

Calculate time series on a pixel level for the CA rasters.
