- Description
- The United States Army Corps of Engineers; Detroit District intends to solicit on a sole source basis under the authority of FAR 6.302-1 to the Oceanweather, Inc.. Only one responsible source and no other supplies or services will satisfy agency requirements. Assistance on creation of a long term-wind and pressure field climatology for the entire Great Lake region has been requested to develop new inundation flood maps water level maps for the Federal Emergency Management Agency. Extreme storm waves and surge heights are used for the flood maps. Providing quality surge and wave estimates in the Great Lakes are dictated by the quality of the forcing functions, namely the winds and pressure fields. Describing the fast moving meteorological events can be accomplished by many methods. One method used for the past decade is the Natural Neighbor Method (NN, D. Beletsky, et al. 2003), spatially interpolating point-source meteorological information (e.g. wind speed, direction, and barometric pressure) producing time varying spatial fields. This method has been used for a series of pilot studies in Lake Michigan involving validation of wave and surge modeling technologies. Results from these tests indicated certain northerly and southerly wind events extending along the central axis of Lake Michigan did not produce an expected spatial coherency in the wind fields. The consequences of this deficiency produced a persistent negative bias in the wave and surge model estimates compared to the measurements. Very recently, a new set of high-resolution meteorological products have been produced. The CFSR archive is based on a re-analysis program of all meteorological products generated by NOAAs National Center for Environmental Predictions. This 31-year archive (1979 to 2009) provides wind and barometric fields on a 0.5-deg global geographical resolution at a one-hour interval. This archive only became available in early 2010, and was not originally considered as a source to be used for the pilot studies. Based on the shortcoming in the NN winds and pressures (i.e., lacking spatial coherency along the central axis of Lake Michigan), the CFSR products were created for a handful of storms in the pilot studies. The CFSR archive was accessed by ERDC CHL staff, the files downloaded, translated from a GRid In Binary (GRIB), and interpolated on the wave model grid. The time required to perform these tasks was significant. Modeling studies conducted to date indicate significant advantages to using the CFSR wind product, and this wind information is needed to maximize the accuracy and quality of modeling studies being done in support of FEMA for all the Great Lakes. Work will be conducted to down-load, translate, and interpolate wind and pressure fields for the entire CFSR archive data set. The interpolation method used would be a bi-linear interpolation. The target domain will encompass all of the Great Lakes including Lake St. Clair and will be bounded by the following longitude and latitudes: LATITUDE: 41.0-deg N to 50.0-deg N LONGUDE: 93.5-deg W to 75.5-deg W The grid resolution should be no greater than 0.02-deg for longitude and latitude. Hourly wind (u and v components), and barometric pressure fields will be generated. Nominal testing of quality in the CFSR fields should be pursued, only to assure time consistency and checks for any discontinuities in the data stream The Government intends to negotiate a firm-fixed price contract on a sole source basis. Interested parties may identify their interest and capabilities to perform the requirements in writing to the identified point of contact no later than 14:00 hrs Eastern Time Zone on 21 July 2010. Your response must demonstrate your firms capabilities, and experience. These will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort with full and open competition, based upon responses to this notice, is solely within the discretion of the Government. Oral communications are not acceptable in response to this notice. No RFP will be issued based upon this Notice of Intent. Interested parties may submit any information for consideration by the government to: LRE-Quotes@usace.army.mil with W911XK-10-T-0096 referenced in the subject line. The estimated dollar value of this procurement is between $10,000 and 20,000
