Users requesting GVI data from SSB should make every effort to supply as much information as possible concerning their needs. If possible, requestors should specify the SSB tape numbers of the tapes to be copied.
Frequently, orders contain incomplete or ambiguous information, which results in delays or improper filling of orders. Proper identification of desired data on magnetic tapes is important because of the high data densities frequently encountered and large volumes of tapes. The following information should be furnished in preparing orders for data to ensure timely and correct completion:
1. Time period of interest. The earliest GVI products were produced for the week of May 10, 1982. Appendices C and D list the time periods for which the First Generation and Second Generation GVI products, respectively, were computed and notes days for which data are not available. Appendix D will be updated periodically; the user may contact SSB for more current information if desired.
2. Which products are desired (see Table 6.0-1):

6.1 GENERAL ORDERING PROCEDURES, SHIPPING, AND PAYMENT
NCDC representatives will take telephone orders and inquiries from approximately 0730 to 1630 Eastern Time, Monday through Friday (except U.S. holidays) at (828) 271-4800. The fax number is (828) 271-4876. Also, Internet can be used to send an electronic message using the following address: satorder@ncdc.noaa.gov.
6.2 PRE-PAYMENT POLICY
Payment is to be made in U.S. funds only, in the form of a check or money order made out to "Commerce/NOAA/NCDC", or VISA or MASTERCARD. Repeat users are urged to set up an account with NCDC (minimum deposit of $1000) to draw upon.
Orders not accompanied by pre-payment will not be processed until full payment is received. U.S. Federal Government Agencies must supply a Purchase Order or MIPR (USA Dept. of Defense contract) with each request.
NOAA organizations must furnish a valid organization code and task number to be billed.
Completed orders are sent via regular mail to domestic customers and via Air Mail to overseas customers; orders valued at more than $250 (U.S.) are sent Registered or Certified Mail. NCDC also has the capability to deliver orders to most areas of the United States, some Canadian locations, and major cities in most Foreign countries, by several different express delivery companies (overnight or two to three days). If any of these express delivery services are requested by the data user, the customer will assume all delivery charges. Delivery to foreign nations can also be made through each nation's Scientific Attaché located at their embassy in Washington, D.C. Such formal arrangements must be requested by the user directly through their Scientific Attaché.
