Delay Statistics

Delay time monitoring

This page shows information on the delivery of scatterometer data for each available satellite-supplier combination.

Here we define delays to be the difference between the observation time and receipt time in the Met Office’s operational meteorological database (MetDB).

There are three types of plot:

  • A delay histogram analysis for “yesterday’s” data, i.e. all available data in the MetDB with observation times in the period 00:00 UTC to 23:59 UTC the day before the plot was made.
  • A delay histogram analysis for the last “month” with statistics accumulated from the 28 previous individual days.
  • A plot of data availability in the MetDB, covering the previous 28 days. A coloured box is plotted for an hour and date if at least one wind was available in that hour. The number of samples* is printed within the box and the color indicates the minimum delay for that hour.

*Since all data in a ‘scan line’ have the same observation time and MetDB timestamps only have a resolution of 1 minute, observations are thinned by sub-sampling to no more than one per minute for each type.
