Air Quality Remote Sensing Program
Aerosol and Smoke Product (GASP)
Algorithm and Data Use Policy
July 26, 2007
GASP data are being distributed at no cost to the users to promote
scientific utilization of the data with the stipulation that the users of
the data agree to follow the policy described below:
- Near Real Time (NRT) products are not necessarily of the same quality as the
archived products. When the archived products are produced the NRT products are
deleted. To control the number of different versions of the data in the
community we require that the users receiving NRT data not distribute them. This
also allows NOAA/NESDIS to notify the data recipients if problems are found with
the data or when we change the algorithm.
- GASP data are produced on a best
effort basis. However, the operational sensor data obtained NRT should not be
used for scientific studies related to climate and similar applications.
- The user of the GASP NRT data are requested to respect the NOAA Publication
Policy described below.
- In publications, presentations, or on web pages
based on GASP data the following acknowledgment should be included.

GASP Algorithm (code)
GASP code is released to those who request for it on a
case by case basis with the approval of NESDIS management. The
person/institution/agency receiving the code must submit a letter stating that
the code will not be distributed without NOAA/NESDIS consent and any errors
uncovered in the code will be first notified to NOAA. Only GASP product obtained
through the NOAA operational system is considered the official product. GASP
generated at places other than NOAA is not endorsed by NOAA and will not
supersede official NOAA Product released through Office of Satellite Data
Product Division (OSDPD). NOAA/NESDIS will not support the user queries on code
implementation and use. Due to time constraints on NOAA staff, the recipient of
the code will not be supported either by NOAA scientists or contractors
regarding the science behind the code, implementation of the code, and
interpretation of the GASP data. Code will be provided after receiving an
official request in the form of a letter which includes language stating the
awareness of these guidelines.
GASP Publication Policy
Production of scientific data from a satellite
instrument requires a team of highly dedicated people whose contributions often
do not get acknowledged in publications. It is strongly advised that in
publications resulting from the use of GASP data relevant members of the
NOAA/NESDIS team be invited to be co-authors. Please contact NOAA/NESDIS air
quality program for recommendations.
NOAA/NESDIS Air Quality Program:
The GASP team consists of the following
members: Shobha Kondragunta
and Istvan Laszlo.
