Met Office - metDB Data: WINPRO data

Brief description

Observations from wind profiling systems.

Observation frequency

Hourly observations from around 400 Wind profiler stations distributed globally resulting in around 10,000 records daily

Delivery and ingest schedule

Data are extracted daily at around 00 UT for the previous day's coverage and delivered to the BADC at around 0200 UT.

Ingest scripts run at the BADC every 20 minutes, converting the incoming files to the self describing BADC-CSV format, but neither the processed or raw data are placed into archive until the following day.

Known problems

There are no known problems with these data.

Additional information

Parameter list

Each station report is a separate record in the file consisting of header information about the station and data section. The header section contains the following information:
