Description

Ozone profile Level 2 (BETA) files provide ozone profile information at a coarser spatial resolution than the native TEMPO resolution by coadding 4across-track pixels in the North-South direction, ~40 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 ozone partial columns at 24 layers with the last layer 0-2 km above the surface, a priori ozone profile and a prior error, total, stratospheric, and tropospheric ozone columns, other retrieved auxiliary parameters, random-noise and total retrieval errors for all of the retrieved quantities, the retrieval averaging kernels for the ozone profile, and the random-noise retrieval error covariance matrix for ozone, and several retrieval quality flags. The retrieval is based on spectral fitting of TEMPO radiances in UV band using the iterative optimal estimation technique with a priori and measurement error constraints.
