Ozone profile Level 3 (BETA) files provide ozone profile 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 ozone partial columns at 24 layers with the last layer 0-2 km above the surface, total, stratospheric, and tropospheric ozone columns, and their random-noise and total retrieval errors, a priori ozone profile and a prior error, effective cloud fraction and effective cloud top pressure. The re-gridding algorithm uses an area-weighted approach.
