Daymet 2018 Data Now Available

Daymet provides high-resolution surface meteorology data for North America.

Daymet provides high-resolution surface meteorology data for North America. The figure shows annual data for the year 2018; Left: Mean maximum daily temperature, Middle: Total precipitation, Right: Mean minimum daily temperature. Daymet data is archived and distributed by the ORNL DAAC.

Daymet weather and climate data for North America are now available for the years 1980 - 2018.

High-resolution reflectance data from the Arctic

Soil Adjusted Vegetation Index

Soil Adjusted Vegetation Index (SAVI) for a site on the Seward Peninsula, Alaska collected on August 14, 2018. SAVI is similar to NDVI, but it suppresses the effects of soil pixels and it uses a canopy background adjustment factor. The reflectance data used to calculate SAVI was collected by the AVIRIS-NG instrument on a flight over the Seward Peninsula, Alaska, on August 14, 2018.

New AVIRIS-NG data from the 2018 ABoVE airborne campaign and an accompanying data processing tutorial are now available.

Soil Carbon Stocks for Tidal Wetlands

Estimated soil carbon stocks (using model results) throughout the Mississippi River delta in Louisiana. Cooler colors (blues and greens) indicate higher soil carbon concentrations.

Researchers with NASA's Carbon Monitoring System estimated the amount of carbon stored in the soil in tidal wetlands of the United States.

Soil Moisture Datasets Become Fertile Ground for Applications
