    "abstract": "PILOT reports describe measurements reported up to four times daily by radiosondes at worldwide fixed land stations. The dataset contains measurements of wind speed and direction. The data are measured from the surface to approximately 20-30 km and measurements are usually taken every 2 seconds. These data are provided as-is from the Met Office and so will need the message components bringing together for each ascent\r\n\r\nThe PILOT data contain the following observations:\r\n\r\nWind speed at standard pressure levels\r\nVertical wind shear\r\nMaximum wind level\r\nThe data comprise vertical profiles of temperature, dew-point temperature, wind speed and wind direction at standard and significant pressure levels. The standard pressure levels are 850, 700, 500, 400, 300, 250, 200, 150, 100, 70, 50, 30, 20 and 10 hPa. Significant pressure levels are calculated according to the Met Office criteria and constitute levels at which significant events occur in the profile, e.g temperature inversions.\r\n\r\nThe data are measured from the surface to approximately 20-30 km. Generally there are up to 4 ascents per day from each station, though some sites may only have 1 or 2 ascents. Ascent times are typically around 00, 06, 12 and 18 UT.\r\n\r\nA maximum wind level is defined as a level at which the wind speed is greater than that observed immediately above and below that level..",
