Description
Four sites along the Kalahari Transect in southern Africa provide short-term measurements of carbon dioxide, water, and energy fluxes from the 2000 wet season campaign. The dataset, collected by NASA researchers, captures vegetation-atmosphere exchange across a north-south aridity gradient on a homogenous sand formation. Measurements include air temperature, CO2 concentration and flux, various radiation components, soil moisture, and wind speed.
Use Cases
Analyzing the relationship between CO2 flux and photosynthetic photon flux density across a precipitation gradient.
Modeling soil heat budget dynamics using concurrent soil temperature and soil moisture measurements.
Investigating water use efficiency in relation to vapor pressure deficit and relative humidity.
Calibrating remote sensing products with ground measurements of infrared surface skin temperature and net radiation.
Studying micro-meteorological conditions via friction velocity, wind speed, and heat flux data.
Strengths
Data captures a controlled climatic gradient across four distinct sites with annual rainfall ranging from 365 mm to 879 mm.
Measurements were collected using the eddy covariance method, a standard for direct flux observation.
The dataset is part of the International Geosphere-Biosphere Programme (IGBP) transect network, providing a standardized context.
Limitations
Row counts and total dataset size are not specified on any platform.
There is a significant conflict in the 'last updated' metadata, with dates ranging from 2000 to 2026.
