Example of AirSWOT radar products in ABoVE Projection at 3.6 m resolution, for a flight over the ABoVE C grid Ch065v034. Left: Shape for backscatter image. Middle: Backscatter magnitude shows bright reflection in the near range and no returns, yielding regions of no data, in the far range. Right: Derived elevation product.
The ABoVE project has released data from AirSWOT flights in Summer 2017 collected over Alaska and Canada.

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.
