The use of IASI data to identify systematic errors in the ECMWF forecasts of temperature in the upper stratosphere
IASI data systematic errors the ECMWF temperature the upper stratosphere
2011/2/25
Since data from the Infrared Atmospheric Sounding Interferometer (IASI) became available in 2007, a number of papers have appeared in the literature which have reported relatively large discrepancies ...
Wave fluxes of equatorial Kelvin waves and QBO zonal wind forcing derived from SABER and ECMWF temperature space-time spectra
Wave fluxes equatorial Kelvin waves QBO zonal wind forcing SABER
2009/6/22
The quasi-biennial oscillation (QBO) of the zonal mean zonal wind is a dynamical phenomenon of the tropical middle atmosphere. Influences of the QBO can even be found at mid and high latitudes. It is ...
Evaluation of upper tropospheric humidity forecasts from ECMWF using AIRS and CALIPSO data
upper tropospheric humidity forecasts ECMWF AIRS CALIPSO
2009/3/13
An evaluation of the upper tropospheric humidity from the European Centre of Medium-Range Weather Forecasts (ECMWF) Integrated Forecast System (IFS) is presented. We first make an analysis of the spin...
Technical note: analytical estimation of the optimal parameters for the EOF retrievals of the IASI Level 2 Product Processing Facility and its application using AIRS and ECMWF data
EOF retrievals IASI Level 2 Product Processing Facility ECMWF
2009/1/4
The Empirical Orthogonal Function (EOF) retrieval technique consists of calculating the eigenvectors of the spectra to later perform a linear regression between these and the atmospheric states, this ...
Evaluation of ECMWF water vapour fields by airborne differential absorption lidar measurements: a case study between Brazil and Europe
ECMWF water vapour airborne differential absorption Brazil Europe
2008/12/22
Three extended airborne Differential Absorption Lidar (DIAL) sections of tropospheric water vapour across the tropical and sub-tropical Atlantic in March 2004 are compared to short-term forecasts of t...
Global isoprene emissions estimated using MEGAN, ECMWF analyses and a detailed canopy environment model
isoprene emissions MEGAN ECMWF detailed canopy environment model
2008/10/31
The global emissions of isoprene are calculated at 0.5° resolution for each year between 1995 and 2006, based on the MEGAN (Model of Emissions of Gases and Aerosols from Nature) version 2 model (Guent...
Equatorial wave analysis from SABER and ECMWF temperatures
Equatorial wave SABER ECMWF temperatures
2008/10/30
Equatorial planetary scale wave modes such as Kelvin waves or Rossby-gravity waves are excited by convective processes in the troposphere. In this paper an analysis for these and other equatorial wav...
