Seasonality of Photosynthetic Performance

SIF for CLM Simulation Year 2010

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.

Three related datasets from the Carbon Monitoring System (CMS) program describe year-round photosynthetic activity in a conifer forest.

Atmospheric Oxygen and CO2 Concentrations

AO2 Measurements

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.

Data collected by the Airborne Oxygen Instrument (AO2) during the Atmospheric Tomography (ATom) airborne campaigns are now available.

Pre-Fire Ecosystem Classifications in Burned Area

Great Slave Lake

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

ABoVE researchers compiled a map of ecosystem states prior to the 2014 & 2015 fires in the Northwest Territories, Canada.

Daymet Developer Among the Web of Science Most Highly Cited

Dr. Peter Thornton in the field for NGEE Arctic

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

The lead developer of Daymet is recognized as a highly cited author in 2019.

Methane Point-Source Emissions

 AVIRIS-NG Flight Lines

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).

Maps of methane plumes were derived from Next-Generation Airborne Visible Infrared Imaging Spectrometer (AVIRIS-NG) flights over California.
