  • The Institute of Meteorology and Climate Research (IMK) Lidar Data are images displaying the polar wind velocity and the polar aerosol concentration. For elevation scans there are figures at azimuth 0, 60 and 120 degrees, for the azimuth scan there are figures at elevations 7, 12 and 17 degrees available. Angles are indicated in the line above the colourscale. Vertical scans have been made at elevation 90 degree. The upper figures are showing polar (radial) velocity, the lower ones aerosol backscatter at the three different angles which are indecated in each figure above the colour scale. The diagrams are showing unaveraged data. They vizualize a snapshot of approx. 10 minutes measurements starting at the time stated in the filename. Data were recorded from the 19th of June 2005 to the 29th of August 2005.

  • The Institute of Meterological and Climate Research Dornier 128 aircraft data were collected at Chilbolton, Hampshire by instruments on the aircraft, between the 22nd of June 2005 and the 14th of July 2005. The dataset includes measurements of wind direction and wind speed, air density, and air temperature. Measurements taken by the Dornier 128 aircraft and stored in this dataset are: static pressure, uncorrected (hPa) barometric altitude (m) radarheight above ground (m) latitude (deg) longitude (deg) true air speed (m/s) velocity over ground (m/s) vertical velocity (m/s) radiation pyranometer top (W/m2) radiation pyranomter bottom (W/m2) radiation pyrgeometer top (W/m2) radiation pyrgeometer bottom (W/m2) air density (kg/m3) fast air temperature (deg Celsius) potential temperature (deg Celsius) filtered mixing ratio (g/kg) mixing ratio Lyman-Alpha (g/kg) wind component west-east (m/s) wind component south-north (m/s) vertical wind component (m/s) wind direction (deg) wind speed (m/s)

  • The dataset contains the data collected by radiosondes, released by IMK, in both Bath and Chilbolton, during the period from the 19th of June 2005 to the 25th of August 2005. The datset contains measurements of: The dataset contains measurements of: Height above sea level (m) Time since midnight (s) Time since midnight (hh:mm:ss) Height above ground (m) Dry-bulb temperature (degree Celsius) Relative Humidity (percentage) Wind speed (m/s) Wind direction (degree true) Pressure (hPa) Potential Temperature (degree Kelvin) Dew-point temperature (degree Celsius) Specific humidity (g/kg) Saturation mixing ratio (g/kg) u-component of wind velocity (m/s) v-component of wind velocity (m/s)
