The Ensemble of Data assimilations and its use in the EPS
On Tuesday, 22 June 2010, ECMWF implemented an Ensemble of Data Assimilations (EDA). The EDA is designed to provide information about the uncertainty in the analysis of atmospheric observations that provides the starting point for ECMWF's forecasts. In this implementation, the output from the EDA is used to improve the representation of initial-time uncertainty in the forecasts of the Ensemble Prediction System (EPS). The result is a more reliable estimation of forecast uncertainty.
The first TV picture from space?
Comparison with corresponding weather maps produced from the ERA-40 reanalysis has led to confirmation that whilst this image is one of the early pictures from TIROS 1, it is certainly not the first.
MACC Products Related to Russian Fires
MACC makes daily estimates of the emission of aerosols from fires detected by satellite measurements of thermal radiation.
Reanalysis confirms record warmth
Consistent with widespread media reports of extreme heat and adverse impacts in various places, the latest results from ERA-Interim indicate that the average temperature over land areas of the extratropical northern hemisphere reached a new high in July 2010.
Reanalysis and Climate Service
The importance of atmospheric reanalysis data for the development of climate services in Europe was highlighted in a keynote address presented by ECMWF to the 10th annual meeting of the European Meteorological Society, held on 13-17 September 2010 in Zürich, Switzerland.
Wind stilling over the continents of the Northern Hemisphere
A study published on 17 October 2010 in the journal Nature Geoscience shows that over the past three decades, surface wind speeds seem to have noticeably decreased in several regions of the world, such as the United States, China, Australia, and in several European countries. Given the often inadequate quality and heterogeneity of wind data measured by anemometers, no long-term study of the evolution of wind speeds on a global scale had been carried out so far.
Co-operation agreement with Israel signed.
On 28 October 2010, Mr Israel Katz, Israeli Minister of Transport and Road Safety, and Mr Dominique Marbouty, Director-General of the European Centre for Medium-Range Weather Forecasts (ECMWF), signed a co-operation agreement at ECMWF’s headquarters.
