Modeled WRF-STILT Footprints for Boston, MA

Data from the WRF-STILT model representing the response of a receptor in Boston, Massachusetts

Estimated surface influence on the carbon dioxide concentration at a receptor in Boston, Massachusetts (ppm/umol m-2 s-1).

Modeled footprint products estimate the influence of upwind surface fluxes on observed carbon dioxide and methane concentrations.

Year-round Data from Alaskan Flux Towers

Three tower sites at Barrow, Alaska

Three tower sites at Barrow, Alaska: Barrow Environmental Observatory (BEO) tower, Biocomplexity Experiment, South (BES) tower, and the Climate Monitoring and Diagnostics Laboratory (CMDL) tower.

NASA's ABoVE campaign provides year-round CO2, CH4, and meteorology at five sites on Alaska's North Slope.

A new RESTful Application Interface (API) has been released for the ORNL DAAC MODIS Web Service.

Daymet Climatologies Updated

Daymet V3 average annual minimum temperature for 1980 and 2015

Daymet V3 average annual minimum temperature for 1980 and 2015 for a subset of the Daymet domain in Alaska and western Canada.

Daymet V3 annual and monthly climatologies for minimum and maximum temperature, precipitation, and vapor pressure have been updated to include year 2017.

Peak Greenness in the Canadian Boreal Forest

The Canadian boreal forest study area and the 46 sites used in the analysis mapped on top of AVHRR NDVI trends from Beck and Goetz (2011)

Sites used in this study are shown with AVHRR NDVI trends from Beck and Goetz (2011). Figure from Sulla-Menashe et al. (2018)

A new ABoVE dataset provides a 28-year time series of peak greenness data derived from Landsat 5 TM imagery over the Boreal forest region of Canada.

Modeled WRF-STILT Footprints for Barrow, Alaska

Plot of the footnearfield1 variable for 0.1 degree gridded STILT footprint model output for August 15,1982 near the receptor location at Barrow, Alaska.

Plot of the 0.1 degree gridded STILT footprint model output for August 15, 1982 near the receptor location at Barrow, Alaska. This variable provides 24 hours of surface influence representing the response of the receptor to a unit surface emission (ppm/umol m-2 s-1) of CO2 in each grid cell within a small region close to the measurement location. (From the data file foot1982x08x15x06x00x71.3230Nx156.6114Wx00016.nc)

Land surface influence on atmospheric CO2 and CH4 concentrations in Barrow, Alaska was simulated for 12 selected years from 1982 to 2011 as part of the ABoVE campaign.

Aircraft altitude and heading for the B-200 aircraft during a flight on July 11, 2016 as shown by the ORNL DAAC Airborne Data Visualization.

Conditions recorded by ACT-America flights over Eastern North America are presented in a new dataset.

AVIRIS-NG Spectra from ABoVE

Hyperspectral imagery captured for ABoVE during a flight of the AVIRIS-NG instrument

Hyperspectral imagery captured for ABoVE during a flight of the AVIRIS-NG instrument over the Alaskan Arctic.

Surface reflectance was measured along more than 400 flight lines during the intensive 2017 ABoVE airborne campaign.

What is New in Daymet 2017?

Daymet single pixel downloads accessed the week of August 14, 2017.

Daymet single pixel downloads in the vicinity of Yellowstone National Park, USA, accessed the week of August 14, 2017.

Daymet now includes gridded climate data through year 2017 and a redesigned data extraction tool.
