Annual expansion of a thaw slump on the East Fork Chandalar River near the community of Venetie, Alaska, from 2008 through 2017. The erosion time series was created by digitizing data from ESRI base maps and Landsat 5, 7, and 8 images. The eroded area appears to be growing steadily, mostly to the east, with apparent limitation on growth to the north and south.

Measurements of atmospheric carbon dioxide concentration from flasks collected by the Medusa system during ATom-4 flights in 2018.

Solar-Induced Fluorescence derived along ERS-2 GOME orbital tracks on 1 July 1995.

See you at AGU, December 9-13 in San Francisco.

Simulated and observed seasonal patterns of canopy SIF (740 nm) for (a, c) absolute SIF and (b, d) normalized canopy SIF for CLM simulation year 2010. Both a satellite SIF product (GOME-2) and the PhotoSpec measurements are included for comparison.

Example cross-sections of CO2, O2, and APO (O2 + 1.1 * CO2) measured by AO2 (interpolated flight track data) and the Medusa flask sampler (filled circles) during the Pacific southbound flights of ATom-4 in April and May 2018.

Ecosystem map for the Great Slave Lake area, Northwest Territories, Canada, for the period 1997-2011.

Dr. Peter Thornton leads the Modeling and Scale Integration Science Team for the Next-Generation Ecosystem Experiments (NGEE) Arctic project.

Example of AVIRIS-NG flight lines over the southern San Joaquin Valley, Kern County, CA, in Fall 2016 and the Vista-CA potential methane emitting facilities and infrastructure for the three primary sectors (energy, agriculture, and waste).
