INTRODUCTION

PURPOSE. The purpose of this document is to provide an overview of and
instructions for access to climatological data available for use by engineers designing
government structures.

SCOPE. The Air Force Combat Climatology Center (AFCCC) compiled the
data in this document at the request of the Air Force Civil Engineer Support Agency
(HQ AFCESA). Sites were identified by AFCESA, US Army Corps of Engineers
(USACE), and the Naval Facilities Engineering Command (NAVFACENGCOM). Final
selection of sites was based upon availability of climatological data. Most are located at
military installations supporting airfield operations, or at local airports/airfields. (See
Chapter 3 for a listing of sites.) Department of Defense (DOD) agencies and DOD
contractors may obtain data for additional sites by providing site coordinates and
elevation in written request to AFCCC/DOO, 151 Patton Avenue, Room 120, Asheville,
North Carolina, 28801-5002. Non-DOD users should contact the National Climatic Data
Center, Federal Building, Asheville, North Carolina, 28801. Nongovernmental site data
may be obtained from a private consulting meteorologist or the following Web site:

ACCESSING THE DATA. To access the data, go to the AFCCC Web site
at http://www.afccc.af.mil/ and follow the instructions in paragraph 1-3.1, 1-3.2, 1-3.3, or
Appendix A.
1-3.1
Retrieving Data for DOD (.mil Domain) Users. Follow the procedures
outlined in Appendix A. Open the data from the site or save it to disk for future viewing.
Each site is presented in an 18-page Adobe Acrobat file (PDF) format and will require
Adobe Acrobat Reader to view the file. To comply with Standard 90.1-2001, Energy
Standard for Buildings Except Low-Rise Residential Buildings, co-sponsored by the
American Society of Heating, Refrigerating, and Air Conditioning Engineers and the
Illuminating Engineering Society of North America (ASHRAE/IESNA) and approved by
the American National Standards Institute (ANSI), the AFCCC has added a separate
file containing all cooling degree-day data based on 50 F for all sites. Paragraph 2-
10.1.3 covers the use of this file in more detail. Bin Temperature Data .csv files are
suitable for importing into Microsoft Excel.
1-3.2
Retrieving Data by World Meteorological Organization (WMO) Number.
Follow the procedures outlined in Appendix A. The product locator W MO menu
requires a six-digit input. Many of the locations in Chapter 3 have five-digit W MO
numbers; therefore, when inputting a five-digit W MO, you must enter a leading zero.
For example: Paris has a W MO number of 71490; input 071490 in the appropriate
space.
