This interface is for the visualization and analysis of EOS Aura TES daily level 3 gridded data. Level 3 daily data (per TES global survey of about 26 hours) are provided at 2° latitude by 4° longitude. The level 3 data are derived from level 2 retrieved parameters at each pressure level using spatial Delauney triangulation and interpolation (over poles extrapolation is used). See the Level 3 User’s Guide for details. Currently, methane (CH4), carbon monoxide (CO), water vapor (H2O), deuterated water vapor (HDO), nitric acid (HNO3), ozone (O3), and atmospheric temperature data are available. Atmospheric temperature is separated into daytime (ascending orbit) and nighttime (descending orbit) measurements. Only nadir observation data are offered, except HNO3 which are limb mode data (see TES global survey availability calendars).
TES daily Level-3 data are available about once every other day. Please see the TES data availability calendar for exact dates with data.
