Air Quality Remote Sensing Program
GOES 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:

  1. 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.
  2. 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.
  3. The user of the GASP NRT data are requested to respect the NOAA Publication Policy described below.
  4. In publications, presentations, or on web pages based on GASP data the following acknowledgment should be included.
    "GOES aerosol optical depth product is provided by NOAA/NESDIS."

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.
