Hi, I would like to know the relative impact of missing weather data on the simulated yields in DSSAT 3.5. For example, what will be the impact on simulated yields, for any given year, of 5 days of weather data missing? of 25 days? of 60 days? When are to many days missing? Will the impact be more important if the missing data is in clusters (let say from Jan 2 to Jan 12) vs in separate dates? Will missing data from one variable have more impact than another variable (for esample, Tmax vs Solar radiation, etc.) thank you for your help Sincerely Jean-Philippe Brassard Département de Géographie Université de Montréal _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp.
