Technical Reports WATCH Technical Report Number 9: Estimation of Land Surface Temperature using AVHRR sensors on the NOAA satellite The theoretical basis for the land surface temperature (LST) and land surface emissivity (LSE) retrieval from the Advanced Very High Resolution Radiometer (AVHRR) is given, using split-window techniques. The algorithms proposed use calibrated reflectances and brightness temperatures from the AVHRR channels 1, 2, 4, 5 as well as NDVI images to produce a global LST. The algorithms can be used globally as they have been simulated from a worldwide emissivity and brightness temperature data base. The cloud tests applied to the LST data are also provided. This document describes the mathematical basis for the algorithms, the ancillary data-sets required and the validation strategy. WATCH, J. A. Sobrino, Y. Julien, V. Hidalgo, J.C. Jimenez, G. Soria, C. Mattar, B. Franch, R. Oltra, J. Cuenca, December 10, 2008 Watch Technical Report Number 8: International Summer School on Hydrological Drought and Global Change Objectives, procedure of the selection of candidates and the programme of the International Summer School on Hydrological Drought and Global Change (Trieste, Italy, 22-27 June 2008) are summarized. The report has a comprehensive set of annexes (e.g. flyer, application form, list of lecturers, list of participants, detailed programme of summer school and handouts for parallel workshops, title of contributions from participants, questionnaire, certificate) which might be useful for following courses. The evaluation of the summer school, which is based upon an extended questionnaire (86% response), covers the major part of the report. The vast majority of the participants was very happy with the summer school. About 90% of the students classified it as good to excellent.
