Experimental Short-Term Drought Indicator Blend
Update Schedule

Last Update

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 is updated every 5 days, with a delay of 4 to 5 days to allow for data collection and quality control.

The short-term blend combines PDSI, Z-Index, 1-month SPI, and 3-month SPI to estimate the overall short-term drought. This product is an example of current NIDIS-funded research. Learn more.
