We had 14 participants (noted above) at the meeting and followed the above agenda. A few relevant points of the meeting include:
  • A GSICS "session" was held as part of the 2014 AOMSUC and for the most part, was well received. In the future, a longer session would allow for more direct interactions with users. It was felt that through this meeting, a three year rotation between a US (AMS Satellite Conference or at NOAA), Europe (EUMETSAT meeting or even IGARSS) and Asia (AOMSUC) could be arranged.
  • It was noted that the next Users Workshop would be held at the 2015 EUMETSAT Satellite Conference (Toulouse, France, 21-24 Sept which incidently coincides with SPIE meeting)
  • At IPWG-7 (Tsukuba, Japan, 17-21 Nov. 2014), the most relevant action to this group would be the request to CGMS members for specific plans regarding the reprocessing of L1 satellite radiances from MW imagers and sounders
  • The AMSR-2 calibration is nearing a new version (March 2015) from JAXA, although there are still some residual differences, mainly at the lower frequencies with TMI and GMI
  • The GMI is performing quite well and will likely become the NASA GPM X-Cal standard in the future. Some recent upgrades include a magnetic anomaly and an across scan bias. X-Cal meets again during January 24-25 in Orlando, FL, USA
  • The SCOPE-CM project for SSM/I is expanding to include SSMIS (March 2015) and SMMR (mid-2016?); its been difficult to track down the original L1 SMMR data so the Pathfinder data set will be used initially
  • It appears that only Tim and Masaaya from the MW SubGroup will be able to attend the GRWG+GDWG meeting in India in March; Tim will explore remote communications buts its likely that we won't have any participation this time
  • Headway is being made with the CEOS MW subgroup so a future joint meeting is being considered
  • Initial thoughts were expressed regarding a MW standard data set, although there were differing opinions and we sort of ran out of time to discuss too deeply.
  • Next meeting in the April timeframe


  • ALL - Edit and finalize meeting minutes/actions
  • Ralph - Contact NASA Ice group about SMMR L1 archive
  • Tim - Explore possibility of remote session in India
  • Cheng-Zhi - Develop a joint list of topics with CEOS MW sub group and also potential meeting dates and location
  • Larry, Manik, Ralph, Tim, Masaaya - Develop user requirements, what our group can do to meet these, and how these can fit within existing GSICS conventions and systems.
