ABoVE

Mapping wildfires across Alaska and Canada

Date of Burning (DoB) was estimated for areas within each fire scar across Alaska and Canada.

Date of Burning (DoB) was estimated for areas within each fire scar across Alaska and Canada. In this figure, red areas are fire scar locations across central Canada in 2015.

New data from NASA's ABoVE project provide maps of the date of burning within fire scars across Alaska and Canada from 2001-2015.

Updated Spatial Grid for ABoVE

An updated version of the standard reference grid for NASA's ABoVE campaign has been released.

Spring Snowmelt Across Alaska

Date of last spring snow cover in 2000

Date of last spring snow cover for portions of Alaska and the Yukon Territory in 2000. Data spatial extent is based on the MODIS sinusoidal projection.

Data from NASA's ABoVE campaign tracks the last day of spring snow cover for parts of Alaska and the Yukon Territory annually from 2000 through 2016.

Vegetation at Alaskan flux towers

Historical data from the ABoVE project characterize vegetation within five flux tower footprints in Alaska.

Global Foliage Clumping Index

Global map of MODIS-derived clumping index in 2006

Global map of MODIS-derived clumping index in 2006 (from He et al. 2012). Clumping index values range from 0 to 1 (maximum clumping to minimum clumping) representing the degree of foliage grouping within distinct canopy structures, such as tree crowns, shrubs, and row crops, relative to a random distribution.

A new dataset provides a high-resolution global clumping index derived from MODIS.
