Jaramillo" From: Dennis Ojima Subject: Re: Greetings Cc: nacp@python.as.harvard.edu, nacp@io.harvard.edu Hi Victor, It is hard to believe that such deeds can be done. Sign of the sad world we live in. Sorry to have been difficult to get hold of, two many details to work out. As for the data sets needed, the kinds of data are soils, land cover, land use, and climate. Soils: characteristics related to soil depth, soil texture (% sand, silt, and clay), rockiness are the basics. In addition some idea of chemcial nature of the soil would be useful, that is CEC (cation exchange capacity, Base Saturation, pH, carbonate content, total of organic and inorganic N and P, %OM. Land cover: vegetation type that would be indicative of the plant community that would be used to interpret vegetation structure, plant functional type characteristics. The IGBP has its 1km global data base, some information to augment the coarse plant functional type info that IGBP would provide. Though, a Mexican version of that mapping would be useful in regard to characterize corrections to classification would be useful. Land Use: Information related to management practices on grazing, fire, forestry management, cropping management. General information regarding stocking rates, fire rotation or frequency, harvesting rotation, off-take rates, plowing methods, N and P inputs, crop rotations would be useful. Though at the first level of info, just know the predominant set of land uses for a particular land unit would be useful. Climate: monthly and/or daily climatology related to air temperatures (max and min), precipitation, relative humidity, solar radiation, cloudiness, wind speed. What a shopping list!!!! This not a minimum requirement list, but represents a set of useful info that can be used for the modeling analysis. It would be useful to see what does exist and characterize this availability in an appendix for the NACP report so that we can indicate where potential data availabilities are and what potential gaps may exist. Thanks much and hope to see you soon again. Cheers Dennis At 06:32 PM 9/11/2001 -0600, you wrote: >Hola Dennis, > >I am still shocked by the recent events!!
