Summary
Data rescue activities. NMA-RO has used sources which were prior identified (listed in deliverable D.1.14) to rescue data at Romanian stations covering time intervals prior to 1960. Monthly bulletins issued by the Romanian Meteorological Service were used and snow data and catchment average precipitation for 17 river basins have been digitized for the interval 1921-1940 (e.g. figure 1). In addition, daily bulletins issued by the Romanian Meteorological Service (from year 1925) have been used as alternative sources to fill some gaps of digitized air pressure data for 2 stations from Northern and Eastern Mediterranean areas (Tripoli and Tanger).

MAIN PROBLEMS of rain gauges: density, quality, instrument types
•Real-time Meteo-France (~1500-1800)
•volunteers (~2800)
Construct a 2007-2010 reference estimate of spatialized precipitation for rain gauges control and validation at fine scale.
PROPOSED SOLUTION
Use radar network in the spatialization process of the
precipitation estimate
Radar data need Radar data need also to be qualifiedalso to be qualified
UEA• Updating of CRU TS 3.1• Paper about to be submitted• Includes Potential Evapotranspiration
using Penman-Monteith formula (FAO)
• Ge Verver will talk about comparisons with ECA&D
DWD and KNMI
