NOAA Surface Weather Observations

The NOAA Surface Weather Observations dataset (NOAA-SWO) (or formerly Data for the Year [DFTY]), is a special data collection comprised of merged NOAA in situ surface observational data, including first-order stations (in particular, stations used in the Local Climatological Data and Climatological Data products) that are subject to manual Quality Control updates (usually deriving from NOAA Form B-14 Corrections to Surface Weather Observations). When data arrives from the SRRS and GTS data feeds, processing is performed upon the data to separate out certain headers and data types. NOAA-SWO is a result of this parsing and merging process, with the addition of manually corrected Microcomputer-Aided Paperless Surface Observations (MAPSO).
