O2-O2 cloud Level 2 (PROVISIONAL) files provide cloud 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 effective cloud fraction (ECF), cloud optical centroid pressure (OCP), scene albedo, scene pressure, ancillary data used in the calculation, and processing quality flags. The ECF is derived from reflectance at 466 nm. The OCP is derived from O2-O2 slant column density. The cloud retrieval uses Look Up Tables (LUTs) of reflectance and air mass factors as a function of geometry, surface albedo, surface pressure and cloud pressure. The O2-O2 cloud 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.
