Assess the potential of MODIS GPP for estimating wheat yield in Montana and North Dakota and 2) define the practical limits within which wheat yield can be sufficiently estimated using these data.
Rangeland Productivity
This study focuses on relating the MODIS eight - day composite LAI, and 16 - day composite EVI and NDVI, to direct measures of above - ground biomass generated within the growing season during four time periods in two steps: 1) establish a methodology for converting plot level biomass measurements to a regional scale; and 2) characterize the relationship between selected MODIS land products and spatially scaled - field observations of grassland vegetation productivity.
MODIS Flux Tower Comparison
Using MODIS and eddy-flux estimates of Gross Primary Production (GPP) data from several climate regimes, we are analyzing the accuracy of the MODIS GPP (MOD17A2) algorithm.
Real-Time Modeling Effort
Ecosystem process models such as Biome-BGC are used to create data gap filling strategies; to provide the component fluxes of both ET and NEE; to identify the relationship between measured NEE and plant biomass; and to resolve scaling issues, allowing point measurements from eddy flux towers to be extrapolated to regional scales.

BOREAS
The Boreal Ecosystem-Atmosphere Study (BOREAS) was a series of NASA funded field, remote sensing and modeling investigations centered around a large-scale international interdisciplinary experiment in the northern boreal forests of Canada. Its goal was to improve our understanding of boreal forests -- how they interact with the atmosphere, their sensitivity to climate change and how they affect the terrestrial carbon cycle.
Freeze/Thaw Transition
The seasonal transition of the land surface from a frozen to thawed state represents the closest analog to a biospheric on/off switch existing in nature, initiating a number of terrestrial processes that are virtually dormant under frozen conditions. Landscape freeze/thaw transitions coincide with marked shifts in albedo, surface energy and mass exchange, including ecological trace gas, snow and river runoff dynamics. This abrupt state transition occurs each year over roughly 50 million km2 of the Earth's terrestrial surface.
African Hydrology
The African Hydrology project aims to quantify the role of changes in climate and land use on hdyrologic processes over the African continent.
Scripps Global CO2
Variations in the amplitude and timing of the seasonal cycle of atmospheric CO2 have shown an association with surface air temperature consistent with the hypothesis that warmer temperatures have promoted increases in plant growth in the northern high latitudes. We present evidence from satellite data that the photosynthetic activity of terrestrial vegetation increased from 1981 to 1991 in a manner suggesting an increase in plant growth associated with an increase in the duration of the active growing season. The regions of greatest increase lie between 45°N and 70°N where marked warming has occurred in the spring time due to an early disappearance of snow. The satellite data are concordant with an increase in amplitude of the seasonal cycle of atmospheric carbon dioxide exceeding 20% since the early 1970s, and an advance in the timing of the drawdown of CO2 in spring and early summer of up to 7 days. Thus, both the satellite data and the CO2 record indicate that the global carbon cycle has responded to interannual fluctuations in temperature which, although small at the global scale, are regionally highly significant.

Assessment of Anthropogenic and Climatic Impacts on the Global Carbon Cycle
Using A 3-D Model Constrained by Isotopic Carbon Measurements and Remote Sensing of Vegetation
NTSG Landcover
The progressive increase in global atmospheric CO2 concentration is well known. It is caused by industrial society burning more fossil fuel, which emits CO2 as a waste product, than the land and ocean photosynthetic organisms can consume in their growth processes. However, the geographic locations of sources and sinks of CO2 from terrestrial vegetation are not well understood. This project combines a computer simulation model, BIOME-BGC, with an annual global climate database to simulate the daily CO2 fluxes from terrestrial vegetation globally at 1x1 degree resolution.
