EOS MLS Near Real-Time Data Products
The MLS team have developed a capability to produce limited data
products in near-real-time. Currently we are processing stratospheric
temperature and ozone data with a latency of typically between 2 to 4
hours distributed by the NASA Goddard Space Flight Center Earth
Sciences Data and Information Service Center (GSFC-DISC).
The Aura MLS NRT data products are derived from a reduced Level-2
algorithm which uses a fast linearized forward model resulting in
computational resource requirements reduced dramatically compared to
the standard product processing suite.
Data Overview
An overview of the Aura MLS NRT products and comparison with the MLS
standard data products is given in a brief user guide:

Data Access
MLS NRT Data Access (there are up to 96 files per day per product each
containing 15 minutes of data).
The Aura MLS version 2.2 Near-Real-Time Ozone and Temperature Data are
available via anonymous FTP download from GEFC-DISC. Only data from
the past 7 days are retained online. However, the MLS team can provide
historical NRT data (in daily files) for offline testing purposes.
Ozone

Order: ftp://auraraw1u.ecs.nasa.gov/data/Aura_NRT/ML2O3_NRT.002/
Temperature

Order: ftp://auraraw1u.ecs.nasa.gov/data/Aura_NRT/ML2T_NRT.002/
Future Plans
We are working on improving the quality of the temperature and ozone
NRT products to extend their range into the upper troposphere and
upper stratosphere/mesosphere. The capability to produce H2O data is also
planned.
