Abstract:
Near real time (NRT) data products from the Microwave Limb Sounder (MLS) on
the Aura satellite are described. MLS-Aura is in a 98 degree sun synchonous
orbit making just shy of 3500 measurements per day with a latitude coverage
from 82 degrees south to 82 degrees north. The measurements are provided with a
latency of less than 3 hours. The MLS NRT products are: Temperature, O3, H2O,
CO, HNO3, SO2, and N2O. The vertical coverage includes the stratosphere and
uppermost troposphere with the lowest altitude pressure level being
261 hPa for O3, 215 hPa for Temperature, CO, and SO2, 147 hPa for H2O and
100 hPa for HNO3 and N2O. The quality of the data set will be described.
Some applications are assimilation into atmospheric models such as the Goddard
Earth Observing System (GEOS) version 5 and supporting field campaigns such as
Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling
by Regional Surveys (SEAC4RS).
