These NCEP ADP operational global synoptic surface data reports were collected from the GTS during time slots centered on the 6-hourly analysis times of their global and regional models. Two types of data were collected and the reports usually include pressure, temperature, dew point depression, wind direction and speed. NCEP also decoded the precipitation data, but only for the U.S. and Canada.
The two types are: 1) data from land stations, including SYNOP, METAR, and beginning in the mid 1990s, AWOS and ASOS reports, and 2) data from moving ship, fixed ship, MARS (moving and fixed), and buoys (moored and drifting).

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
