Material on this page is from NASA Air Quality Data Pathfinder. The following sections will help guide you to topic-specific data and resources for accessing, visualizing, preparing/manipulating (e.g. subsetting), and analyzing data. Each observation, model, and reanalysis data has unique characteristics that should be considered when evaluating its use. Datasets referenced in this pathfinder are from a variety of sources including satellites, airborne, and field campaign in situ data. Additional datasets use these remotely-sensed data as inputs for models that can be used to forecast future conditions. Please note that many satellites/platforms carry multiple sensors.
An asterisk (*) next to an entry indicating that near real-time (NRT) data products are available through NASA’s Land, Atmosphere Near real-time Capability for EOS (LANCE). While not intended for scientific research, NRT data are good resources for monitoring ongoing or time-critical events. To learn more about the difference between NRT and Standard Science Products, see Near Real Time versus Standard Products.
