Licensing Agreement

Important: This Agreement stipulates the conditions concerning the implementation and usage of the radiative transfer code SMARTS. This Agreement is legally binding; it must be read and accepted before the download process can start. Indicating "I accept" signifies that the User adheres to the terms of this Agreement. This constitutes a legal replacement for his/her signature and date.

This copy of the SMARTS (Simple Model of the Atmospheric Radiative Transfer of Sunshine) program package (hereafter, the Program) is provided free of charge to the User under the conditions that:

  1. The User recognizes that the Program is the intellectual property of its Author, Dr. Christian A. Gueymard.
  2. The Program is not to be used for commercial purposes. Inclusion of part or totality of the program into any software or product may be done without the Author's preliminary acceptance only if it is distributed free of charge.

  4. The Program is not to be given to a third party without the explicit agreement of its Author or representative.
  5. The User refers to these publications whenever the use of the Program is mentioned:
    • Gueymard, C. (2001). "Parameterized Transmittance Model for Direct Beam and Circumsolar Spectral Irradiance." Solar Energy (71:5); pp. 325–346.
    • Gueymard, C. (1995). "SMARTS, A Simple Model of the Atmospheric Radiative Transfer of Sunshine: Algorithms and Performance Assessment." Professional Paper FSEC-PF-270-95. Florida Solar Energy Center, 1679 Clearlake Rd., Cocoa, FL 32922.
  6. Neither the Author nor the institution through which this copy of the Program is obtained can be held responsible for the consequences of programming errors, inaccuracies, or misuse.
  7. Even though the Program is regularly updated to reflect progress in atmospheric radiative transfer, no guarantee is expressed about its accuracy under all possible conditions of use.
