3. NWS Calibration Workshop, LMRFC March, 2009 3 Sources of Data for Calibration National Climatic Data Center (NCDC) –Hourly precipitation (thru Feb, 2008 for legacy programs, 2005 for Browser) –Daily precipitation (through May, 2008 for legacy programs, 2005 for Browser) –Max, min temperature –Snow on Ground –Synoptic Data –Evaporation data. U.S. Geological Survey (USGS) –Mean daily flow –Peak flow –Lake elevation –Pool elevation –Storage –Measurements (note: recently removed due to concerns) –Hourly Discharge (provisional) http://ida.water.usgs.gov/ida/ http://ida.water.usgs.gov/ida/

4. NWS Calibration Workshop, LMRFC March, 2009 4 Sources of Data for Calibration, cont’d RFC Archives from NOAA Hydrologic Data System –NEXRAD –OFS Processed Data Base (PRD) –Point data and other Postgres data RFC Archived Data Base Natural Resources Conservation Service (NRCS) –Snotel data IFLOWS (higher elevation data)

5. NWS Calibration Workshop, LMRFC March, 2009 5 Accessing Data for Calibration Legacy programs on NHDS web site –Station Inventory –Daily Transfer –Hourly Transfer –Syntran (evaporation data) Historical Data Browser (HDB) –GUI replacement of legacy programs

6. NWS Calibration Workshop, LMRFC March, 2009 6 Meta Data ( station inventory, history, on flat file, 2008 ) OHD RFC Data on NOAA1 Server (2008) Meta Data ( station inventory, history) on Postgres ‘OB9_Histdata’, to 1999, soon to be updated Web Access Legacy programs (stand alone) Historical Data Browser (AWIPS) FTP Historical Data Access for Calibration Data Flow: Current System

7. NWS Calibration Workshop, LMRFC March, 2009 7 Accessing Data for Calibration In future we hope to have: –Updated Calibration System within CHPS Incorporate –CAP –ICP –OPT3 –HDB –GIS –Access to NCDC and USGS directly

11. NWS Calibration Workshop, LMRFC March, 2009 11 RFC Data A recent request for old NWSRFS data triggered an effort to retrieve all archived NWSRFS data for the period from 1996-Sept 2005. The data has been extracted from tape and placed on an OHD server. An inventory of NWSRFS files was then created on a RFC-by-RFC basis and can be found at: http://amazon.nws.noaa.gov/hdsb/data/nwsrfs/nwsrfs.html. If you would like to request any old NWSRFS data, please email your request to nhdsinfo@gateway2.nws.noaa.gov.
