AOPC-Meeting XX GSNMC Report
ECV Precipitation
• Satellite records have entered into climate time scales reaching the 30yrs limit (Jörg Schulz to elaborate on this, will have a 1-day meeting by 7 April to complete the entire Precip-Input)
• GTS based holdings and products improving
• Automation of networks tremendously increases the volume of observations in many networks
• Holdings of historic data continuously growing but access and rescue to historic records remains a challenge. Still substantial delays until data arrives with GPCC and/or information becomes accessible.
• Certain areas remain in particular challenging when it comes to data sharing.
• Main reasons are either administrative or technical issues whereby the latter ones often stem from encoding problems with regard to the WMO data formats (BUFR/GRIB). XML based formats being OGC compliant might bear the potential to alleviate technical obstacles.

AOPC-Meeting XX GSNMC Report
• GEWEX launched new initiative to tackle remaining uncertainties in quantification of the global water cycle -> Related BAMS paper discussed yesterday
• Arctic precipitation remains a particular challenge
• Fort he studying of extremes, sub-daily and hourly information is crucial. Here the higher automation and in the long run radar networks will enhance the observational regime substantially.
• For radar data first initiatives to harmonize reflectivity formats have taken place (Workshop in Exeter)
• Combined rain-gauge products developed in many countries (Australia, Netherlands, France, Germany). In Germany it runs in operational mode to consult federal flood warning agencies, and decadal-reanalysis of a harmonized re-processing are about to accessed for climatological studies.
• Better Integration of 4 (!) obs regimes (in-situ, satellite, radar and micro-links still requires research and development and scientific exchange
