TIMED Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) O₃, CO₂, and H₂O Mixing Ratios, O, O₂, OH, and NO Volume Emission Rates, and also National Meteorological Center, NMC, Neutral Temperature Density, and Pressure, Version 2.07, Level 2A (L2A), 42 s Data

The Sounding of the Atmosphere using Broadband Emission Radiometry, SABER, Instrument is one of four Instruments on the NASA Thermosphere Ionosphere Mesosphere Energetics Dynamics, TIMED, Satellite. The primary Goal of the SABER Experiment is to provide the Data needed to advance our understanding of the fundamental Processes governing the Energetics, Chemistry, Dynamics, and Transport in the Mesosphere and Lower Thermosphere. SABER accomplishes this with Global Measurements of the Atmosphere by using a 10-Channel Broadband Limb-Scanning Infrared Radiometer covering the Spectral Range from 1.27 µm to 17 µm. These Measurements are used to provide Vertical Profiles of Kinetic Temperature, Pressure, Geopotential Height, Volume Mixing Ratios, VMR, for these Trace Species: Ozone, O₃, Carbon Dioxide, CO₂, Water, H₂O, Atomic Oxygen, O, and Atomic Hydrogen, H. These Measurements also used to provide Volume Emission Rates, VER, for 5.3 µm NO, 2.1 µm OH, 1.6 µm OH, and 1.27 µm O(¹Δ), Cooling Rates and Heating Rates for many CO₂, O₃, and O₂ Bands, and Chemical Heating Rates for seven important Reactions.

The Cause of the Errors was determined to be unaccounted for Spectral Out-of-Band Radiance in the H₂O Channel centered at 6.8 µm arising from Ozone Emission in the 9.6 µm Band. The corrected SABER Radiances have been used to produce a long-term H₂O Database labeled as Version 2.07. Water Vapor Volume Mixing Ratio (VMR) Vertical Profiles are now available in the SABER Data Archive covering the Stratosphere and Mesosphere extending from near the Tropopause at approximately 100h Pa, about 16 km Altitude, up to the Mesopause Region at approximately 0.006 hPa, about 83 km Altitude, and over the Time Period from January 25, 2002 to the present Day.
