TEMPO formaldehyde total column V02 (NRT) (PROVISIONAL)
Formaldehyde Level 2 (PROVISIONAL) files provide trace gas information at TEMPO’s native spatial resolution, ~10 km^2 at the center of the Field of Regard(FOR), for individual granules. Each granule covers the entire North-South TEMPO FOR but only a portion of the East-West FOR. The files are provided in netCDF4 format, and contain information on vertical columns, ancillary data used in air mass factor calculations and reference sector corrections, and retrieval quality flags. The retrieval uses a three-step approach: (1) spectral fitting of slant columns, (2) air mass factor calculation and derivation of vertical columns, and (3)reference sector corrections. The formaldehyde 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.
