Methane emissions from wetlands

Global monthly 0.5-deg by 0.5-deg wetland methane emissions from (a) the full ensemble (2009-2010) and (b) extended ensemble (2001-2015). From Bloom et al. (2017).

Monitoring Arctic Vegetation for ABoVE

Vegetation (Vaccinium uliginosum-Thamnolia vermicularis in the foreground) on Unalaska Island, August 10th, 2007 (Talbot et al., 2010).

Vegetation on Unalaska Island, August 10th, 2007 (from Talbot et al., 2010).

Ten recently published data sets provide historical environmental, soil, and vegetation data collected at study locations throughout Alaska.

FLIR data from CARVE flights

Infrared radiance of the land surface measured by the FLIR instrument onboard the CARVE flight on April 3, 2013.

A new data set provides measurements from the Forward Looking Infrared (FLIR) camera aboard the CARVE aircraft.

WRF-STILT footprints from CARVE

Surface contours (50% --- blue; 80% --- purple) for the average WRF-STILT influence functions (mid-afternoon averages 2012-2014) show CO2 and CH4 measurements from the CARVE tower have a high sensitivity to the boreal forests and lowlands of interior Alaska. Cyan and red circles are shown for the footprints after filtering (from Karion et al., 2016).

Surface contours for the average WRF-STILT influence functions show CO2 and CH4 measurements from the CARVE tower have a high sensitivity to the boreal forests and lowlands of interior Alaska (from Karion et al., 2016).

Two CARVE data sets provide modeled surface influence for particle receptors located at positions along CARVE flight paths and selected tower locations.
