Spatio-temporal trends in the hydroclimate of Turkey for the last decades based on two reanalysis datasets [PDF]
Hydrology and Earth System Sciences, 2016 We present a regional assessment of the spatiotemporal trends in several hydro-climate variables from 1979 to 2010 in Turkey, one of the countries of the eastern Mediterranean vulnerable to climate change, using the two reanalysis products of the ECMWF ...

Age of stratospheric air in the ERA-Interim [PDF]
Atmospheric Chemistry and Physics, 2012 Abstract. The Brewer-Dobson mean circulation and its variability are investigated in the ERA-Interim over the period 1989-2010 by using an off-line Lagrangian transport model driven by analysed winds and heating rates. At low and mid-latitudes, the mean age of air in the lower stratosphere is in good agreement with ages derived from aircraft, high ...

Ice supersaturated regions: properties and validation of ERA-Interim reanalysis with IAGOS in situ water vapour measurements [PDF]
Atmospheric Chemistry and Physics, 2020 Cirrus clouds and their potential formation regions, so-called ice supersaturated regions (ISSRs), with values of relative humidity with respect to ice exceeding 100 %, occur frequently in the tropopause region. It is assumed that ISSRs and cirrus

Brief communication: Evaluation of the near-surface climate in ERA5 over the Greenland Ice Sheet [PDF]
The Cryosphere, 2020 The ERA5 reanalysis, recently made available by the European Centre for Medium-Range Weather Forecasts (ECMWF), is a new reanalysis product at a high resolution replacing ERA-Interim and is considered to provide the best climate reanalysis over Greenland

An intercomparison of subtropical cut-off lows in the Southern Hemisphere using recent reanalyses: ERA-Interim, NCEP-CFRS, MERRA-2, JRA-55, and JRA-25 [PDF]
, 2020 Four recent reanalysis products ERA-Interim, NCEP-CFSR, MERRA-2 and JRA-55 are evaluated and compared to an older reanalysis JRA-25, to quantify their confidence in representing Cut-off lows (COLs) in the Southern Hemisphere.

Real‐time correction of ERA‐Interim monthly rainfall [PDF]
Geophysical Research Letters, 2013 Gridded precipitation from reanalysis can be a valid proxy for observations in many regions where local measurements are not available. Despite the continuous improvements in assimilation systems and the growing availability of in situ and remote observations, model errors can nevertheless still affect reanalysis quality.

Estimating trends in atmospheric water vapor and temperature time series over Germany [PDF]
Atmospheric Measurement Techniques, 2017 Ground-based GNSS (Global Navigation Satellite System) has efficiently been used since the 1990s as a meteorological observing system. Recently scientists have used GNSS time series of precipitable water vapor (PWV) for climate research. In this work,

Wave Extremes in the North East Atlantic from Ensemble Forecasts [PDF]
, 2013 A method for estimating return values from ensembles of forecasts at advanced lead times is presented. Return values of significant wave height in the North-East Atlantic, the Norwegian Sea and the North Sea are computed from archived +240-h forecasts of

The Brewer–Dobson circulation inferred from ERA‐Interim
Quarterly Journal of the Royal Meteorological Society, 2011 AbstractThe transformed Eulerian mean residual circulation is calculated from ERA‐Interim for 1989–2009. Known as the Brewer–Dobson circulation, this measures the tropical upwelling of mass from troposphere to stratosphere, the mean meridional mass transport in the stratosphere and the downwelling of mass in the Extratropics.
