Data Source Description
Sources: UC Merced, Climate Engine
Drought blends data from Climate Engine were available in raster format.
These experimental blends integrate several key drought monitoring products and indices into a single short-term or long-term product, based on the methodology developed at the NOAA Climate Prediction Center (CPC). The blends are created using the Climate Engine tool, and apply the CPC weighting ratios to the high-resolution gridMET gridded research dataset. The data are updated daily, with a delay of 3 to 4 days to allow for data collection and quality control.
The long-term blend combines PDSI, Z-Index, and 6-month, 1-year, 2-year, and 5-year SPI to estimate the overall long-term drought.
