One of the filesystem used by the SABER data server to serve Version 2.0 Level2A and Level2B files became unstable
in early November and began corrupting data files before being taken offline for maintenance on November 22. We have temporarily replaced that filesystem and
restored SABER data files through November 12, 2013. However, any data downloaded from November 1 through November 22 may be corrupted and should be downloaded again. Data production was resumed in early December.
The Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument is one of four instruments on NASA's TIMED (Thermosphere Ionosphere Mesosphere Energetics Dynamics) 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 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 for the trace species O3, CO2, H2O, [O], and [H], volume emission rates for 5.3 µm NO, 2.1 µm OH, 1.6 µm OH, and 1.27 µm O2(1Δ), cooling and heating rates for many CO2, O3, and O2 bands, and chemical heating rates for 7 important reactions.
