|ABoVE||Arctic-Boreal Vulnerability Experiment|
The Arctic-Boreal Vulnerability Experiment (ABoVE) is a NASA Terrestrial Ecology Program field campaign that will take place in Alaska and western Canada between 2016 and 2021. Climate change in the Arctic and Boreal region is unfolding faster than anywhere else on Earth. ABoVE seeks a better understanding of the vulnerability and resilience of ecosystems and society to this changing environment.
|AirMOSS||Airborne Microwave Observatory of Subcanopy and Subsurface|
The goal of NASA’s Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) investigation is to provide high-resolution observations of root-zone soil moisture over regions representative of the major North American climatic habitats (biomes), quantify the impact of variations in soil moisture on the estimation of regional carbon fluxes, and extrapolate the reduced-uncertainty estimates of regional carbon fluxes to the continental scale of North America. The AirMOSS campaign used an airborne ultra-high frequency synthetic aperture radar flown on a Gulfstream-III aircraft to derive estimates of soil moisture down to approximately 1.2 meters. Extensive ground, tower, and aircraft in-situ measurements were collected to validate root-zone soil measurements and carbon flux model estimates. The AirMOSS soil measurements can be used to better understand carbon fluxes and their associated uncertainties on a continental scale. Additionally, AirMOSS data provide a direct means for validating root-zone soil measurement algorithms from the Soil Moisture Active & Passive (SMAP) mission and assessing the impact of fine-scale heterogeneities in its coarse-resolution products.
|BOREAS||Boreal Ecosystem-Atmosphere Study|
The Boreal Ecosystem-Atmosphere Study was a large-scale international interdisciplinary experiment in the boreal forests of central Canada. Its focus was improving our understanding of the exchanges of radiative energy, sensible heat, water, CO2 and trace gases between the boreal forest and the lower atmosphere. A primary objective of BOREAS was to collect the data needed to improve computer simulation models of the important processes controlling these exchanges so that scientists can anticipate the effects of global change, principally altered temperature and precipitation patterns, on the biome.
|BOREAS_FO||Boreal Ecosystem-Atmosphere Follow-On |
The Boreal Ecosystem-Atmosphere Study (BOREAS) Follow-On Project extended and built upon the original BOREAS goal to investigate interactions between the boreal forest biome and the atmosphere in order to clarify their roles in global change. A common set of existing BOREAS in-situ and remote-sensing data were compiled at point, study area, and regional scales for use by Follow-On investigators. Follow-On investigations were integrative, interdisciplinary, and focused on modeling and regional-scale analyses. The development and intercomparison of the various carbon, water, and energy flux models was a major objective. Additional information on the BOREAS Follow-On project is available in the campaign guide document.
|CARVE||Carbon in Arctic Reservoirs Vulnerability Experiment|
The Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) is a NASA Earth System Science Pathfinder Mission. From 2011 to 2015, CARVE collected airborne measurements of atmospheric carbon dioxide, methane, and carbon monoxide and relevant land surface parameters in the Alaskan Arctic. Continuous ground-based measurements provide temporal and regional context as well as calibration for CARVE airborne measurements. CARVE provides an integrated set of greenhouse gas data that provides experimental insights into Arctic carbon cycling.
|CMS||Carbon Monitoring System (CMS)|
The NASA Carbon Monitoring System (CMS) is designed to make significant contributions in characterizing, quantifying, understanding, and predicting the evolution of global carbon sources and sinks through improved monitoring of carbon stocks and fluxes. The System will use the full range of NASA satellite observations and modeling/analysis capabilities to establish the accuracy, quantitative uncertainties, and utility of products for supporting national and international policy, regulatory, and management activities. CMS will maintain a global emphasis while providing finer scale regional information, utilizing space-based and surface-based data and will rapidly initiate generation and distribution of products both for user evaluation and to inform near-term policy development and planning.
|FIFE||First ISLSCP Field Experiment (FIFE)|
The FIFE Project was a large-scale climatology project set in the prairies of central Kansas in 1987 and 1989.

|FIFE_FO||First ISLSCP Field Experiment Follow-On |
The First ISLSCP (International Satellite Land Surface Climatology Project) Field Experiment (FIFE) project conducted field studies on a prairie site in Kansas from 1987 to 1989. The FIFE Follow-on work included additional analyses of data collected during the initial field campaigns and additional field measurements. The objectives of both FIFE and FIFE Follow-on were to understand the biophysical processes controlling the fluxes of radiation, moisture, and carbon dioxide between the land surface and the atmosphere, and to develop remote-sensing methodologies for observing these processes.
|LBA||Large Scale Biosphere-Atmosphere |
The Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) is an intensive scientific investigation of the tropical rainforest of Brazil and portions of adjacent countries. Like FIFE and BOREAS, this project uses intensive remote-sensing techniques and ground-based experiments to investigate the atmosphere-biosphere-hydrosphere dynamics of this large tropical region. The LBA Project encompasses several scientific disciplines, or components. The LBA-ECO component focuses on the question: "How do tropical forest conversion, regrowth, and selective logging influence carbon storage, nutrient dynamics, trace gas fluxes, and the prospect for sustainable land use in Amazonia?"

|VEMAP||Vegetation-Ecosystem Modeling & Analysis|
A multi-institutional, international effort whose goal is to evaluate the sensitivity of terrestrial ecosystem and vegetation processes to altered climate forcing and elevated atmospheric CO2. Phase 1 of the VEMAP project developed a model database of climate, soils, and vegetation compatible with the requirements of three ecosystem physiology models and three vegetation lifeform distribution models. Phase 2 developed a historical (1895-1994) gridded data set of climate (temperature, precipitation, solar radiation, humidity, and wind speed) and transient climate change scenarios based on coupled atmosphere-ocean GCM experiments, such as those with elevated greenhouse gases and sulfate aerosols.
The Model Archive allows users to evaluate the uncertainties of model results in comparison to results from other models in assessment/policy studies. In addition, the archived models allow users to see how models treat individual processes (source code) and what the model inputs were (state parameters, spin-up data, driving variables). For each model the DAAC will have documentation, source code (with version number), input data, example output data, and post-processing or analysis code (if applicable).
