Hallo Model users! I have this questions: 1) Has anyone the experience with the measurement of the temperature on the plant surface, if yes, could you recommand me some device (I suppose on the principle of the longwave radiation)? 2) Did anybody try to exchange air temperature, which is usually used like basic meteorological input with the surface temperatute of the plants, in model simulation? What were the results? What is your opinion about this exchange? Thank you for your time, Zdenek ********************************************************************** dr.Zdenek Zalud Mendel University of Agriculture and Forestry Institute of Bioclimatology Zemedelska 1 613 00 BRNO Czech Republic Europe tel: 00 425 4513 3083 fax: 00 425 4531 2044 e-mail: [log in to unmask] **********************************************************************
