Study Description

In some parts of the country, rainfall maps have not been updated for approximately 50 years. That means we are ignoring the last 50 years of rainfall data in our basic hydrologic estimates for drainage structures. NOAA has updated parts of the country in various volumes of NOAA Atlas 14 with funding through regional climatic centers and other pooled funding arrangements. NOAA's National Weather Service (NWS) proposes updating precipitation frequency estimates for the states not included in NOAA Atlas 14 Volume 1 (AZ, southeast CA, NM, NV, UT), Volume 2 (DE, DC, IL, IN, KY, MD, NC, NJ, OH, PA, SC, TN, VA, WV), and Volume 3 (PR, VI). The proposal includes updating estimates for the Pacific Island dependencies. The updates will be published as subsequent Volumes of NOAA Atlas 14 "Precipitation-Frequency Atlas of the United States"; on the web at www.nws.noaa.gov/ohd/hdsc;. The solicitations are by climatic regions. This particular solicitation is for the Southeastern Region and is of interest to the following States: AL, FL, GA and MS.

Objectives

The purpose of this study is to determine annual exceedance probabilities (AEP) and average recurrence intervals (ARI) for durations ranging from 5 minutes to 60 days and for ARIs from 1 to 1,000 years. The point estimates will be spatially interpolated to a spatial resolution of approximately 4km x 4 km. The study results will be published as volumes of NOAA Atlas 14, a wholly web based publication available at www.nws.noaa.gov/ohd/hdsc. The publication will include the artifacts provided in Volumes 1 and 2 including access through the Precipitation Frequency Data Server, base grids in standard formats, electronic copies of maps, results of trend analyses, charts of seasonal distributions and probabilistic temporal distributions, and detailed documentation. Updated areal reduction factors are being developed as a separate appendix to NOAA Atlas 14 for the entire U.S. including Alaska.The project will review and process all reasonably available rainfall data. It is recognized that the rainfall data archived by NOAA's National Climatic Data Center (NCDC) may not be sufficient to accomplish the objectives of this project. Therefore, other data available from sources such as State Climatologists and other Federal, State and local agencies will be examined and included if appropriate. The state of the art techniques and processes developed and applied for NOAA Atlas 14 Volumes 1 and 2 will be applied. They include regional frequency analysis based on L-moments including error estimates, a combination of PRISM based techniques and CRAB for spatial interpolation, techniques for the analysis of climatic trend, temporal distribution and seasonality, internal consistency checks and variety of automated processes designed to enhance productivity. Intermediate results in the form of hourly and daily estimates at several ARIs will be distributed for peer review as will the final documentation.

Scope of Work

The attached proposed Statement of Work by NOAA provides detailed information on the following:

Task 1 - Data Collection and Quality Control

Task 2 - Regionalization

Task 3 - Frequency Distribution Selection and Fitting Studies

Task 4 - Frequency Calculations

Task 5 - Short Duration Estimates

Task 6 - Internal Consistency at Observing Locations

Task 7 - Spatial Interpolation and Consistency

Task 8 - Mapping and other Spatial Artifacts

Task 9 - Temporal Distributions

Task 10 - Peer Reviews

Task 11 - Documentation

Task 12 - Final Deliverables

Task 13 - Status Reporting
