Similar to OMPS on SNPP, OMPS on board NOAA-20 and NOAA-21 carries nadir mapper OMPS-NM
and
nadir profiler OMPS-NP. NOAA-21 also carries OMPS-LP similar to SNPP but NOAA-20 does
not
carry OMPS-LP.
NOAA-20 and NOAA-21 provide higher resolution than OMPS SNPP.
Sulfur dioxide (SO2) produced from volcanoes and anthropogenic sources is also monitored
by
OMPS.
OMPS provides near real-time data to detect, monitor, and characterize SO2 and ash
injected
into the atmosphere from volcanic eruptions.
Data from OMPS is used to assess the impacts of volcanic eruptions on air traffic
control
operations globally.
