Abstract:
We describe collaborative project between NASA’s Direct Readout Laboratory (DRL) and ozone processing team, JPL/Caltech, Geographic Information Network of Alaska (GINA), and Finnish Meteorological Institute (FMI) to expedite the processing and delivery of polar-orbiting meteorological satellite direct readout (DR) volcanic SO2 data to Alaska Volcano Observatory, Anchorage Volcanic Ash Advisory Center, European Support to Aviation Control Service, as well as their operational users. Addressing critical need for night-time northern polar coverage, we have developed low latency volcanic SO2 products based on the thermal infrared (TIR) data acquired by the VIIRS instruments aboard the polar orbiting operational weather satellites. Our SO2 software packages are designed for DRL International Planetary Observation Processing Package (IPOPP) environment and run operationally at both GINA and FMI ground stations. FMI combines DR data from GINA on its website http://sampo.fmi.fi/so2_comp.html and provides data to EUMETCast users. Together, these two ground stations provide nearly complete coverage of the Arctic, while DRL delivers all IPOPP applications to a broad DR user community worldwide.
