UMRBPP Surface: Hourly and Special METAR Surface Observation Data Set 1.0 General Description This is one of the surface data sets developed for the Upper Missouri River Basin Pilot Project (UMRBPP). The UMRBPP took place in the region surrounding the Black Hills in SD and WY during the period from 5 April to 5 May 1999. This data set includes the hourly and special METAR surface observations from 39 locations over the UMRBPP region. See Section 2.0 for a list of sites and information on the type of instrument used at each site. The observations were typically made hourly, but when certain criteria were met, special observations were made. These data were retrieved from the Pennsylvania State University METAR database for the period of the UMRBPP. 2.0 Station Information ID Type Site Name Lat Long Elev (ft) ------------------------------------------------------------------ K0V1 NWS ASOS Custer, SD 43-43-59N 103-36-41W 5661 KCUT NWS ASOS Custer, SD 43-43-59N 103-36-41W 5661 K2WX NWS ASOS Buffalo, SD 45-36-16N 103-32-47W 3003 K9V9 NWS ASOS Chamberlain, SD 43-46-00N 099-19-06W 1703 KAIA EXP ASOS Alliance, NE 42-03-26N 102-48-00W 3926 KANW NON AWOS Ainsworth, NE 42 34 38N 100 00 01W 2588 KBFF NWS ASOS Scottsbluff, NE 41-52-01N 103-35-09W 3947 KBHK EXP ASOS Baker, MT 46-20-52N 104-15-27W 2961 KBIS NWS ASOS Bismarck, ND 46-46-15N 100-45-38W 1652 KBYG EXP ASOS Buffalo, WY 44-22-53N 106-43-08W 4911 KCDR FAA ASOS Chadron, NE 42-50-14N 103-05-52W 3315 KCPR NWS ASOS Casper, WY 42-53-51N 106-28-23W 5320 KCYS NWS ASOS Cheyenne, WY 41-09-07N 104-48-22W 6120 KD07 NWS ASOS Faith, SD 45-01-55N 102-01-09W 2574 KDGW EXP ASOS Douglas, WY 42-47-39N 105-22-55W 4919 KDIK FAA ASOS Dickinson, ND 46-47-59N 102-47-59W 2586 KEFC Manual Belle Fourche, SD 44 40' N 103 51' W 3019 KGCC NWS ASOS Gillette, WY 44-20-22N 105-32-31W 4330 KGDV FED AWOS Glendive, MT 47 08 18N 104 48 18W 2456 KGEY EXP ASOS Greybull, WY 44-30-57N 108-04-33W 3908 KHEI EXP ASOS Hettinger, ND 46-00-38N 102-38-59W 2716 KIEN EXP ASOS Pine Ridge, SD 43-01-32N 102-31-23W 3274 KISN NWS ASOS Williston, ND 48-10-26N 103-38-12W 1900 KLAR FAA ASOS Laramie, WY 41-18-59N 105-40-20W 7269 KLBF NWS ASOS North Platte, NE 41-07-19N 100-40-06W 2779 KMBG NWS ASOS Mobridge, SD 45-33-00N 100-24-31W 1673 KMLS FAA ASOS Miles City, MT 46-25-36N 105-52-57W 2628 KN60 NWS ASOS Garrison, ND 47-38-45N 101-26-22W 1910 KOGA NON AWOS Ogallala, NE 41 07 10N 101 45 39W 3244 KPHP NWS ASOS Philip, SD 44-03-04N 101-36-04W 2206 KPIR FAA ASOS Pierre, SD 44-22-53N 100-17-08W 1728 KRAP NWS ASOS Rapid City, SD 44-02-44N 103-03-14W 3166 KRCA Manual Ellsworth AFB, SD 44 09' N 103 06' W 3214 KSDY FED AWOS Sidney, MT 47 42 24N 104 11 30W 1980 KSFD EXP ASOS Winner, SD 43-23-22N 099-50-34W 2040 KSHR NWS ASOS Sheridan, WY 44-46-10N 106-58-08W 3943 KSNY FAA ASOS Sidney, NE 41-05-58N 102-59-08W 4288 KVTN NWS ASOS Valentine, NE 42-51-31N 100-33-05W 2587 KWRL FAA ASOS Worland, WY 43-58-21N 107-57-21W 4172 KY22 Lemmon, SD 45 56' N 102 10' W 2566 ASOS = Automated Surface Observing System AWOS = Automated Weather Observing System FAA = Federal Aviation Administration NWS = National Weather Service EXP = Experimental FED = Federal NON = Non-Federal 3.0 Detailed Information 3.1 Custer, SD ASOS Commissioning The observations from Custer, SD during the UMRBPP came out under two different station identifiers (K0V1 and KCUT). Observations were taken using K0V1 from 1 April to 18 UTC on 9 April. The ASOS site was still uncommissioned during this time. Starting at 1809 UTC on 9 April the ASOS station at Custer, SD was commissioned and was renamed KCUT.
