Description

Level 1 radiance (PROVISIONAL) files provide radiance 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 radiometrically calibrated and geolocated radiances for the UV and visible bands, corresponding noise, nominal wavelength grid, geolocation, viewing geometry, quality flags and other ancillary information. The product is produced using the L0-1b processor which includes multiple steps: (1) Image processing to produce radiometrically calibrated radiance, (2) Image Navigation and Registration (INR) using GOES-R data, and (3) post INR processing geolocation tagging. The Level 1 radiance 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, with Level 1 products being available earlier than Level 2 cloud and trace gas products). 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.
