Restricted Data Information Site
Main Topics
As more and more sources of input data become available for use in numerical
modeling and research at NCEP, there are certain situations where a data
provider, in return for access to and use of their data, may place restrictions
on the circumstances under which such data may be redistributed to persons
outside of the community of NCEP Central Computer System (CCS) users. Any
data that is prohibited from being fully and freely redistributable to the
general public is considered to be
restricted. NCEP is required to honor
all restrictions placed on the data we receive from any provider. Each
type of restricted data has its own unique set of requirements, which are
explained in further detail below. In general however, whenever any data
is restricted, the restriction remains in force regardless of any reformatting,
rearrangement, or method of presentation of the data. For example, restricted
data cannot be graphically plotted on a web page that is accessible to the
general public. Likewise, quality-controlled data values that are directly
derived from restricted data are themselves also subject to the same
restriction(s) as the original data.
There are currently five data types that are restricted.

of the inherent restrictions as well as any special requirements,
