ML2SO2_NRT is the EOS Aura Microwave Limb Sounder (MLS) Near-Real-Time (NRT) product for sulfur dioxide (SO2). This product
contains daily SO2 profiles taken from the 240 GHz band. The most recent 7 days of data are available. Spatial coverage is
near-global (-82° to +82° latitude), with each profile spaced 1.5° or ~165 km along the orbit track (roughly 15 orbits per
day). The recommended useful vertical range of NRT Sulfur Dioxide profiles is 215 - 10.0 hPa. There are about 96 NRT files
per day containing roughly 15 minutes or less of data each.
Before using these data, please download both the MLS version 3.4 NRT User Guide which describes the NRT algorithm and data
quality, as well as the MLS Level-2 Data Quality Document for Standard Products which describes the caveats for using MLS
SO2 data. MLS documentation can be found at http://disc.sci.gsfc.nasa.gov/Aura/additional/documentation/.
Users are encouraged to register with the MLS team at http://mls.jpl.nasa.gov/ to obtain updates and information about this
product from the MLS team.
The MLS NRT data are not as accurate as the retrievals that constitute the standard MLS products, but nevertheless the results
are of scientific use and track the standard MLS products with reasonable fidelity. NRT sulfur dioxide profiles are only recommended
for scientific use at pressure levels from 215 hPa to 10.0 hPa.
