Joint GEO-CAPE CEOS AC-VC Workshop: Brad Pierce gave a presentation summarizing regional ozone (O3) and nitrogen dioxide (NO2) Observation System Simulation Experiments (OSSEs) at the GEOstationary Coastal and Air Pollution Events (GEO-CAPE) Science Team Meeting at the NOAA Center for Weather and Climate Prediction, College Park, Md. The GEO-CAPE Science Team meeting was held in conjunction with the 14th Committee on Earth Observation Satellites (CEOS) Atmospheric Chemistry – Virtual Constellation (AC-VC) workshop, which focused on development of future greenhouse gas and air quality low earth orbit and geostationary constellations and synergies with meteorological satellite constellations.

Figure caption: There are three major components of the chemical OSSE framework: Nature run (teal), Radiative Transfer/Retrieval System (purple), and Analysis System (orange). A set of representative profiles from 17 sites (hourly, every 3rd day of July 2011) and full radiative transfer/Optimal Estimation Retrievals (UV, UV-VIS, UV-VIS-TIR) were used to generate input data for developing a multiple regression estimate of the averaging kernels (AK). The AK regressions and the full Nature atmosphere were used to generate the Regional Multiple Regression AK retrievals for three multi-spectral wavelength combinations (UV, UV-VIS, UV-VIS-TIR). Observed GOES East and West Sounder cloud masks were used to identify clear retrievals, which were fed into the WRF-Chem/GSI regional assimilation system. The GEO-CAPE O3 OSSE showed systematic and significant increase in lower to mid tropospheric correlations and reductions in rms errors and biases when hourly geostationary UV, UV-VIS, and UV-VIS-TIR ozone retrievals are assimilated, respectively. 

JPSS Arctic Summit: The JPSS Arctic Summit was held this week in Anchorage, Alaska. The 4-day meeting was divided into several topics. Andrew Heidinger and Michael Pavolonis led panels on cloud and volcanic ash applications. Jeff Key led the discussion of the JPSS cryosphere products in the Arctic Initiative Meeting, and a demonstration of JPSS ice products done in collaboration with the Alaska Sea Ice Program (ASIP). Multiple University of Wisconsin Cooperative Institute for Meteorological Satellite Studies (CIMSS) scientists also participated and presented, includng Kathy Strabala, Aaron Letterly, Rich Dworak, Jay Hoffman, Jordan Gerth, and William Straka. The meeting provided JPSS-funded scientists access to various Alaska stakeholders from multiple agencies and was attended by roughly 50 people. A report is being generated that will include actions from each of the sub-groups of the summit. The meeting will continue in Fairbanks, Alaska next week. (A.
