NCEP ADP Operational Global Upper Air Observations, December 1972 - February 2007
|
|
These NCEP ADP operational global synoptic upper air data reports were collected form the GTS during time slots centered on the 6-hourly analysis times of their global and regional models.
The groups include ADPUPA, AIRCFT, SIRSOB, SATWND and AIRCAR.
The ADPUPA includes 20 mandatory levels of data from 1000mb to 1mb. All groups include data for various levels, such as "significant level" and flight level. The reports may include pressure, geopotential height, temperature, dewpoint depression, wind direction and speed.
The ADPUPA data includes upper air station data from land and ship
launched radiosondes and pibals.
The AIRCFT data includes aircraft flight level reports from commercial,
military and reconnaissance sources.
The SIRSOB data subset includes satellite infrared sounding observations.
The SATWND data includes satellite winds derived from cloud drift analysis.
The AIRCAR data comes from aircraft takeoffs and landings.
