Evaluation of ECMWF water vapour analyses by airborne differential absorption lidar measurements: a case study between Brasil and Europe
Airborne Differential Absorption Lidar (DIAL) observations of tropospheric water vapour over Brazil and between Brazil and south Europe in March 2004 are compared to 1-hourly short-range forecasts of the European Centre for Medium Range Weather Forecasts (ECMWF). On three along-flight sections across the tropical and sub-tropical 5 Atlantic between 28◦ S and 37◦N humidity fields are observed wh...

متن کاملEvaluation of ECMWF water vapour fields by airborne differential absorption lidar measurements: a case study between Brazil and Europe
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 the European Centre for Medium Range Weather Forecasts (ECMWF). The humidity fields between 28 S and 36 N exhibit large inter air-mass gradients and reflect typical transport patterns of lowand mid-...
متن کاملA comparison of ground-based Doppler lidar and airborne in situ wind observations above complex terrain
Airborne wind observations collected by the National Oceanic and Atmospheric Administration’s (NOAA) WP-3D aircraft are compared with the winds retrieved by the NOAA/Environmental Technology Laboratory’s ground-based scanning Doppler lidar within the Wipp Valley during the Special Observing Period of the Mesoscale Alpine Programme. Comparisons are performed along individual ight tracks and ov...
متن کاملPotential of airborne lidar measurements for cirrus cloud studies
Aerosol and water vapour measurements were performed with the lidar system WALES of Deutsches Zentrum für Luftund Raumfahrt (DLR) in October and November 2010 during the first mission with the new German research aircraft G55-HALO. Curtains composed of lidar profiles beneath the aircraft show the vertical and horizontal distribution and variability of water vapour mixing ratio and backscatter r...
