The Harvard QCLS (DUAL and CO2) instrument package contains 2 separate optical assemblies and calibration systems, and a common data system and power supply.
The QCLS instrument package was used to measure atmospheric concentrations.
The UCATS system is three different instruments in one enclosure: a two-channel chromatograph with electron capture detectors (one measures N2O and SF6, the other measures CH4, H2 and CO), a tunable diode laser instrument for H2O, and a dual-beam O3 photometer.
A new dataset was collected using the Unmanned Aircraft Systems (UAS) Chromatograph for Atmospheric Trace Species (UCATS).
(A) Digital map of soil organic carbon (kg/m2) at 1 m depth and 90 m spatial resolution. The black and blue colored areas are urban areas and water bodies. (B) An area in northern Mexico illustrating the level of detail achieved by mapping across 90 m grids.
Estimates of soil organic carbon are now available from Mexico at a 90 meter resolution.
The Single Pixel Extraction Tool allows a user to obtain daily Daymet data in a tabular format for a single geographic point (pixel) specified by latitude and longitude.
Daymet gridded estimates of daily weather parameters are now available for the years 1980 to 2019.
The ORNL DAAC provides a variety of resources for creating, submitting, and using data products and services.
The ORNL DAAC welcomes your feedback on existing learning resources and suggestions for new ones.
Trends in maximum annual NDVI for natural vegetation within the Greater Yellowstone Ecosystem (GYE) from 1989 to 2014 (Emmett et al. 2019).
Daymet and North American Carbon Program (NACP) data were used to study Normalized Difference Vegetation Index (NDVI) trends across the Greater Yellowstone Ecosystem.
The Earth Science Data and Information System (ESDIS) Project manages the operations of EOSDIS including Distributed Active Archive Centers (DAACs) like the ORNL DAAC.
The ORNL DAAC's social media presence is moving to @NASAEarthData.
Global maps of above and belowground biomass carbon density: (a) aboveground biomass carbon density, (b) belowground biomass carbon density.
Temporally consistent and harmonized global maps of aboveground and belowground biomass carbon density are now available.
The UWG meets once per year to review the status of ORNL DAAC operations and to provide recommendations.
Christine Laney, Isaac Larsen, Alexey Shiklomanov, and Ying Sun have joined the ORNL DAAC User Working Group.
Example of color-infrared imagery shown alongside the corresponding semi-automated open water classification at Old Crow Flats, Alaska.
Over 3,000 km2 of open surface water were mapped from AirSWOT flight lines made in Summer 2017 for the Arctic-Boreal Vulnerability Experiment (ABoVE).
