Metric Information

Climate, vegetation, and drought can be monitored many different ways through ground observations, gridded weather and climate data, and airborne and satellite remote sensing. Access to Google Earth Engine’s satellite image and meteorological collections allow for efficient near real-time drought monitoring through statistical analyses of surface temperature, vegetation, precipitation, snow cover, surface water, soil moisture, evapotranspiration, and simple water balances.

Precipitation

• Standardized Precipitation Index (SPI)

Water Balance

• Palmer Drought Severity Index (PDSI)

Evapotranspiration

• Evaporative Demand Drought Index (EDDI)

Vegetation

• Normalized Difference Vegetation Index (NDVI)
• Enhanced Vegetation Index (EVI)
• Energy Release Component (ERC)

Water/Snow

• Normalized Difference Water Index (NDWI)
• Normalized Difference Snow Index (NDSI)

Drought Blends

• Short & Long Term Drought Blends

Wildfire Risk

• Wildfire Risk to Communities
