European Climate Assessment Analyse extremes in temperature and precipitation in Europe for the 20th century

Approach: climate indicators Short-list compiled with climate indicators for temperature and precipitation Daily resolution improves description of (changes in) extremes Indicators are based on fixed thresholds and percentiles thresholds to account for different climates in Europe

Temperature extremes

Warm spells winter 1976-99

Cold spells winter 1976-99

Precipitation extremes

Data quality Quality control Homogeneity analysis metadata

Remarks Final ECA-report published spring next year Data available (ECD) on cd-rom and web: http://www.knmi.nl/samenw/ecd Follow-up project and data updates ?
