TRAVEL AND MEETINGS:

CIMSS Participation in WMO Rolling Review of Requirements Workshop: The World Meteorological Organization (WMO) held a "ESAC Coordinators and AA PoCs (Hybrid) Workshop" September 22-24, 2025. The workshop was part of the Rolling Review of Requirements (RRR) program, which has defined new Earth System Application Categories (ESAC) and Application Areas (AA) within each ESAC. Jeff Key, Cooperative Institute for Meteorological Satellite Studies (CIMSS), participated as the lead for the Cryosphere ESAC. He gave two presentations and part of a third, covering the status of the Cryosphere Statement of Guidance (an observational gap analysis), metrics for the "uptake" of all the Statements of Guidance, and experiences of the cryosphere group with the WMO Observing Systems Capability Analysis and Review Tool (OSCAR). The workshop agenda and presentations are available online. (J. Key, CIMSS, 608-890-4239)

PUBLICATIONS:

New Publication on History of DMSP in Tropical Cyclone Applications: An article published in the Bulletin of the American Meteorological Society, with authors from the Cooperative Institute for Meteorological Satellite Studies (CIMSS) and the Cooperative Institute for Research in the Atmosphere (CIRA), describes how Defense Meteorological Satellite Program (DMSP) sensors first appearing in the 1980s have significantly contributed to global Tropical Cyclone (TC) monitoring, whether it be from an operational or R&D perspective. Novel LEO DMSP sensor attributes included extremely sensitive nighttime visible imaging, scanning geometries, and spectral channels with pioneering observing capabilities. This article presents historical developments as well as contemporary achievements with a focus on TC applications as the last of the sensors age off, and emphasizes the cross-agency connections that illustrate how civilian and military satellite programs complement and can leverage each other.
