Socioeconomic Data and Applications Center (SEDAC) Collection of Treaty Texts
Entry ID:
CIESIN_SEDAC_ENTRI_TEXTS_COL
Summary
Abstract:
The Socioeconomic Data and Applications Center (SEDAC) Collection of Treaty Texts consists of environmental treaty texts that are compiled in collaboration with the Columbia University Center for International Earth Science Information Network (CIESIN), United Nations Environmental Programme (UNEP), Tufts University's Fletcher School of Law and Diplomacy (FSLD), British Columbia Ministry of ...
 Purpose: To provide search and retrieval of texts of multilateral environmental agreements (MEAs).

WARNING: EP TOMS started experiencing calibration problem since 2002. For data beginning in year 2000, the calibration has been stabilized relative to NOAA-16 SBUV/2 in the equatorial zone. Because of continuing changes in the optical properties of the front scan mirror that are not well understood, data are showing a latitude dependent error that cannot be corrected by a simple calibration correction. The calibration appears to be stable near the equator. But by 50 degrees latitude, there is now a -2% to -4% error in TOMS, a bit larger in the northern hemisphere than in the southern hemisphere. Because of this error, data since 2002 should NOT be used for trend analysis
