The National Climatic Data Center (NCDC) is the collection center and custodian of all United States weather records. It is the central source of historical weather information, some of which it publishes as serial or periodic publications. The Center responds to inquiries for statistical weather data, such as temperature, precipitation, and wind. It can provide daily and hourly weather observations along with monthly and annual summaries, 30-year normals for various meteorological elements, solar radiation data, and various weather maps and charts. Requests for services should define type of data required, stations or geographic limits involved, desired medium (magnetic tape, diskette, hard copy, or microform), and other pertinent information, such as a description of what the data will be used for. SERVICE LIMITATIONS: Work is performed on a reimbursable basis. Unit costs have been established for some services; the requestor can be provided with a cost estimate before work begins. Prepayment is required.
NCDC publishes monthly: storm data, hourly precipitation data, and world climate data; climatological data for each State, and local climatological data for about 280 metropolitan areas are issued both monthly and annually. Various other weather-related publications are produced periodically. A publications list is available, and most publications can be purchased either by subscription or individual copy. Most published data is also available in electronic medium.
