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.

ABoVE Data Measure Arctic Greening

A new study of long-term NDVI trends across the North Slope of Alaska presents high-resolution growing-season NDVI from MODIS.

Field Measurements After Alaskan Wildfires

Forest plots in Tanana, AK

Researchers with NASA's ABoVE field campaign measured burn severity in spruce forests that burned in 2015 near Tanana, Alaska.

Accessing ABoVE Airborne Data

A new tutorial, available on our Resources page, demonstrates how to get ABoVE airborne data sampled at a specific field site.

Year-round Soil CO2 Measurements in Alaska

Sites of forced diffusion chamber deployment

Forced diffusion chambers were established at the seven sites along a south-to-north transect from near Fairbanks to Toolik Lake, Alaska.

Soil surface CO2 efflux in Alaska is available from the ABoVE field campaign.
