Communication with WGCV/ MWSG luqf@cma.gov.cn Qifeng Lu National Satellite Meteorological Center ,CMA
The communications with CEOS/WGCV 1. the Focus Group Meeting of CEOS WGCV Microwave Sensors Subgroup on August 27, 2018 1:00pm-5:30pm is mainly on the Calibration/Cross-Calibration of Microwave Scatterometers, but Kurtis Thome, the chair of WGCV, was there. I talked in the last several slides about this cooperation we agreed between the two groups. After that, Curtis Thome responded positively and further he had a personal communication with me on this topic. 2. On 28 AUG Xiaolong Dong presented in the MW Subgroup Report to highlight we agreed to cooperate between WGCV and GRWG on the potential NRT inter-calibration products for microwave imagers and our planed work. 3. In the WGCV-GSICS interactions on 29 AUG, our concept and actions was fully discussed again.
Interaction with GSICS-Microwave Subgroup and joint work for Cal/val of passive microwave sensors Organize a research group in collaboration with GSICS MW group, to identify and confirm the requirement for pre-launch calibration; Development of techniques for re-calibration/re-processing of historical data.
Passive Microwave Imagers: Current and Planned
Requirement for GSICS Microwave: At CGMS-46 Draft list of plenary actions resulting from CGMS-46 discussions (11 June 2018): https://www.cgms-info.org/Agendas/WP/CGMS-46-CGMS-WP-29 WGI actions open from previous plenary sessions (at CGMS-46) Actionee AGN item Action # Description Action feedback/ closing document Deadline Status HLPP ref GSICS F A46.xx On passive microwave observations: GSICS is requested to organise an expert meeting on the intercalibration of operational PMW sensors to meet the WIGOS 2040 targets for a coordinated effort to share information on current and future PMW instruments and report to CGMS-47 (CGMS-46-EUM-WP-14) CGMS-47 OPEN Future Joint Meeting between the CEOS/WGCV and GSICS microwave groups: CEOS/WGCV develop better instrument design strategy and pre-launch calibration algorithms by learning the knowledge of data quality issues and inter-calibration algorithms from GSICS group. GSICS develop better re-calibration and inter-calibration algorithms by learning the instrument design and pre-launch calibration issues from the CEOS/WGCV group
GSICS MW group focuses and WGCV MSSG focuses Inter-calibration Data standards WGCV MWSG focuses supporting GSICS requirements: Priorities of specific activity areas for interaction with GSICS Prelaunch calibration for characterization of sensors Guidelines/standards for prelaunch calibration: specifications, procedures and processing Postlaunch CAL/VAL for monitoring of calibration parameters, by collaborating with GSICS MW group Standards toward SI traceability of MW radiometric reference (passive/active noise standards)
