• Description: This repository contains the code and data to perform monthly water balance calculations using remote sensing and in situ data for the Central Valley (CV) and Central Valley Watershed (CVWS) of California. Files describing the geographic domain are stored in the shape directory. Scripts to download and process data, and generate figures and results are stored in the code directory. Instructions to install the required software dependencies are in the build directory. Figures and images are stored in the images directory. Below is a list of URLS containing additional datasets for the CV and CVWS.
