TEMPO gridded formaldehyde total column V02 (NRT) (PROVISIONAL)

Formaldehyde Level 3 (PROVISIONAL) files provide trace gas information on a regular grid covering the TEMPO field of regard for nominal TEMPO observations. 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 formaldehyde vertical columns, ancillary data used in air mass factor calculations and reference sector or de-striping corrections, and retrieval quality flags. The re-gridding algorithm uses an area-weighted approach. 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.
