As part of the SPARC (Stratosphere-troposphere Processes And their Role in Climate) water vapour assessment (WAVAS-II), satellite measurements taken from, or coincident with, seven sites from which ground-based microwave instruments measured water vapor in the middle atmosphere.
News & Events for 2017
Ozonesonde data are among the most popular observations in NDACC because the profiles are a mainstay of satellite calibration and are used to develop climatologies used in atmospheric chemical-climate models. Sonde data are used for analysis of lower stratospheric ozone trends, where satellites alone often do a poor job.
The resolution from the International Association of Meteorology and Atmospheric Sciences (IAMAS) was released on November 22, 2017. This resolution specifically stresses the importance of continuation and enhancement of Earth Observation systems to monitor the atmosphere, ocean and other elements of the Earth system.
The proposal from the Australian Bureau of Meteorology for NDACC affiliation for four Dobson measurements was discussed and approved at the 2017 NDACC Steering Committee Meeting in Boulder, Colorado. The measurements were formally invited as NDACC Affiliated shortly thereafter.
The annual meeting of the international Steering Committee (SC) for NDACC was held 6–10 November 2017 in Boulder, CO, USA at the National Center for Atmospheric Research (NCAR).
