The geopotential height of the 500 hPa pressure surface shows approximately how far one has to go up in the atmosphere before the pressure drops to 500 hPa (i.e. 500 millibars). On average this level is around 5.5 km above sea level, and it is often referred to as a steering level, because the weather systems beneath, near to the Earth's.

This report explores ways to describe Sea Surface Temperature (SST) and Sea Ice Concentration (SIC) suitable for next generation reanalyses at ECMWF. To make a long-term time series, we first evaluate two high-resolution SST/SIC products: HadISST2 and OSTIA. HadISST2 is considered for the historical period, while OSTIA would support the near-real-time reanalysis ECMWF provides a web interface to quickly download a sample dataset for evaluation.

ECMWF forecast data. The ECMWF reforecast dataset consists of a 15-member ensemble reforecast computed once weekly from 0000 UTC initial conditions for the initial dates of 1 September to 1 December. The years covered in the reforecast dataset were from 1982 to 2001. The model cycle 29r2 was used, which was a spectral model with triangular truncation at wavenumber 255 (T255) and 40 vertical. ERA-Interim represents a major undertaking by ECMWF (European Centre for Medium-Range Weather Forecasts) to produce a reanalysis with an improved atmospheric model and assimilation system which replaces those used in ERA-40, particularly for the data-rich 1990s and 2000s, and to be continued as an ECMWF Climate Data Assimilation System (ECDAS) until superseded by a new extended reanalysis The datasets presented here have been divided into three categories: Output data, Source data, and Intermediate data. The Berkeley Earth averaging process generates a variety of Output data including a set of gridded temperature fields, regional averages, and bias-corrected station data.

Since there are scarce meteorological stations and a lack of continuous data in Nepal, ECMWF data was selected for temperature and precipitation variables as inputs for the model Negative values show where ECMWF forecasts temperatures lower than those forecast by GFS. The numerical difference between temperatures at 850 hPa forecast by ECMWF and GFS. Positive values show where ECMWF forecasts heights larger than those forecast by GFS This includes different observation data sets of sea surface temperature (SST), sea-ice concentration (SIC), and in situ observations; updates in bias estimation and observation quality controls; and a new method in ensemble generation and initialization. Impacts of these updates have been assessed with data assimilation experiments, normally at a reduced resolution in order to reduce computing cost. It is worth pointing out that improvements from these updates presented in this section may. Monthly data for air temperature (T) and precipitation (P) from ECMWF were compared with the data from 771 ground stations (National Meteorological Institute, INMET) in the state of Minas Gerais in southeastern Brazil for 1979-2017. Potential evapotranspiration was estimated by Thornthwaite method (1948), and water balance was estimated by the method proposed by Thornthwaite and Mather (1955), with an available water capacity of 100 mm. We temporally and spatially compared the two data.

ECMWF has implemented a significant resolution upgrade and methodology for high-resolution forecasts (HRES) and ensemble forecasts (ENS) beginning January of 2016. HRES is now performed via a transform grid with a nominal grid point spacing of 9 kilometers (0.08 degrees), and is carried out with IFS (Integrated Forecast System) model cycle CY41r2. Improvements in computational efficiency and effective resolution have been brought about by implementing a triangular cubic octahedral reduced.

He has over 30 years experience in many different aspects of data assimilation. He worked at the UK Met Office and has been at ECMWF for the last seven years. Abstract Meteorological reports from aircraft are an important source of data for Numerical Weather Prediction. Based on the 36 year ECMWF ERA‐Interim reanalysis data set from 1979 to 2014, the relative changes of global PWV for 1 K rise in temperature are simulated according to the Clausius‐Clapeyron equation. For each grid point, surface temperature, temperature lapse rate, and relative humidity profile are derived by averaging the 36 year data. By using these parameters, PWV can be integrated for.
The ECMWF-derived surface pressure (P s) used to calculate the ZHD and the weighted mean temperature (T m) calculated based on the layered ECMWF data are also evaluated using radiosonde data with RMSE values of 1.14 hPa and 1.24 K, respectively. Consequently, the final CMONOC-derived PWV at 249 stations is obtained and compared with radiosonde-derived and ECMWF-derived PWV while the RMSE.
