TEMPO gridded NO2 tropospheric and stratospheric columns V02 (NRT) (PROVISIONAL)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/is-40e/tempo/no2_nrt_l3.002
Nitrogen dioxide Level 3 (PROVISIONAL) files provide trace gas information on a regular grid covering the TEMPO field of regard for nominal TEMPO observations.
Description
Level 3 files are derived by combining information from all Level 2 files constituting a TEMPO East-West scan cycle. The files are provided in netCDF4 format, and contain information on tropospheric, stratospheric and total nitrogen dioxide vertical columns, ancillary data used in air mass factor and stratospheric/tropospheric separation calculations, and retrieval quality flags.
The re-gridding algorithm uses an area-weighted approach. The nitrogen dioxide near real-time (NRT) files are produced using a fast version of the TEMPO baseline retrieval processor. The TEMPO NRT products are useful for applications with low-latency requirements (<2-3 hours after observation is taken).

The NRT processing optimizes radiance calibration, image navigation and registration, and cloud and trace gas retrievals for rapid processing, while ensuring that product quality is sufficient for most NRT applications.
