Coverage is global but predominantly in UK waters. Measurements include mean sea level pressure, air temperature and humidity (with capabilities for sea surface temperature (SST) and wind speed, wind direction and max gust speed from a limited number of systems). On occasion there may be gaps in the dataset.

Data quality is considered, monitored, compared against background fields and addressed in near real-time throughout its entire life cycle, with suspect data being flagged both automatically and by manual input. Regular, scheduled inspections take place, checking the accuracy of instruments as well as logger software and data formats.
