Featured Projects
NASA's Applied Remote Sensing Training (ARSET) program teaches people to use Earth-observing data in their environmental management and decision-making.
At night, satellite images of Earth capture a uniquely human signal—artificial lighting. Remotely-sensed lights at night improve our understanding of interactions between human systems and the environment.

THORpex is a ten-year international research program to accelerate improvements in short range weather predictions and warnings over the Northern Hemisphere.
The global thunder hour dataset aims to create a core set of global observations to study weather long term.
TolNet provides high spatio-temporal measurements of ozone from near the surface to the top of the troposphere.
TOTE-VOTE took place in the Pacific region with the goal of gaining a better understanding of background transport processes from tropical/polar regions to midlatitudes.
TRACE-A studied the photochemical and meteorological features contributing to enhanced ozone concentrations over the tropical Atlantic Ocean, and characterized primary and secondary ozone precursors associated with biomass burning in South America and southern Africa.
TRACE-P characterized the Asian outflow in terms of chemical composition over the northwestern Pacific and characterized the chemical evolution of the outflow.
TRACER-AQ aimed to better understand the photochemistry and meteorological impact on ozone formation in the Houston region and provide observations for evaluating air quality models and satellite observations.
TransCom aims to quantify and diagnose the uncertainty in inversion calculations of the global carbon budget that result from errors in simulated atmospheric transport.
