SISCAL demonstrator terms of access to Earth observation
data
- AVHRR: The AVHRR instruments are operated by NOAA (National Oceanographic and
Atmospheric Administration, US). No fee or
license requirement is raised by NOAA to directly receive HPRT data from the
AVHRR instruments (http://noaasis.noaa.gov/NOAASIS/ml/satservices.html).
Within SISCAL, AVHRR HPRT data are received, pre-processed and
subsequently made available to SISCAL by the Institute of Meteorology of the Free University of Berlin (FUB). AVHRR data used within
SISCAL are thus copyrighted by FUB. FUB provides AVHRR data to
SISCAL free of charge for demonstration purposes.
- MODIS: The MODIS instruments are operated by NASA. The MODIS instruments on board
the satellites Aqua and Terra constantly broadcast data free of charge for anyone with
the right equipment and software (see http://directreadout.gsfc.nasa.gov/index.cfm).
Within SISCAL, MODIS data are obtained directly from NASA, either
automatically from the rolling ftp archives or through dedicated orders for
specific case studies. MODIS data are free of charge for any use. In the
event that MODIS data, or results using MODIS data, are published, the following
acknowledgement shall be given: "The data
used in this study were acquired as part of the NASA's Earth Science Enterprise. The algorithms were
developed by the MODIS Science Teams. The data were processed by the MODIS
Adaptive Processing System (MODAPS) and Goddard Distributed Active Archive Center (DAAC), and are archived
and distributed by the Goddard DAAC."
- SeaWiFS: The use of SeaWiFS data is regulated by the
NASA data policy. Scientific users who want to have access to SeaWiFS
data products through SISCAL must register with NASA prior to ordering SeaWiFS data products from the SISCAL service. The
application form to become an authorised SeaWiFS
data user can be accessed under http://seawifs.gsfc.nasa.gov/SEAWIFS/LICENSE/checklist.html.
SeaWiFS data or derived products from SISCAL
shall not be used, reproduced, or disclosed for commercial or operational
purposes.
- MERIS: The use of ENVISAT data, namely MERIS and AATSR data, is
covered by the announcement of opportunity (AO) 1398 of which the former
coordinator of the SISCAL project, Prof. Richard Santer
(ULCO / LISE) is the principle investigator. SISCAL data products derived from ENVISAT
data shall not be used, reproduced, or disclosed
for commercial or operational purposes.
