Chile
Rodrigo Delgado UrzúaUniversidad de La Frontera
Temuco, [email protected]
Workshop FONDECYT 1030809La Serena, 21-23 November 2004
KAMM / CMCC Meteorology Group @ Temuco
Researchers: Dr. Sonia Montecinos Dr. Jaime Bustos M. Sc. Jesús Ruiz
Students: Luis Machuca Gabriel Toro Luis Cortes Rodrigo Delgado …
Pollution problem @ Temuco
High concentrations of PM10 in winter (mar-sep) Peaks of 800 μgr/m3, 24h concentrations peaks of
270 μgr/m3 (1)
92% of the emissions come from houses (2)
KAMM-DRAIS Model Input
Meteorological Data: NCEP/NCAR Reanalysis
Emissions data: no data, estimations based in a 1996 study ~ 330 ton/year
Soil-use data: estimated Soil water content data:
estimated Topographical data: taken from
internet databases

Temuco Project Universidad de La Frontera
Center for Modeling and Scientific Computation + Faculty of Engineering, Sciences and Administration + Department of Physics Sciences
DIDUFRO: Estudio de la Meteorología de la IX Región en Condiciones de Invierno (Meteorological study of IX Region in winter conditions)
Temuco Project: Objectives Make a characterization of a
“meteorologically typical” winter day Understand the outputs generated by
KAMM Graphical representation of the model
output data
Computational Adaptation of the Model
KAMM @ Germany: Vector computer (VPP)
KAMM @ Temuco: High-End PC (x86 platform, 2.0 GHz, 2 GB RAM)
Only meteorological model running, dispersion section (DRAIS) not yet implemented
Grid: 144x114 (2x2 Km2), 25 levels
KAMM @ Temuco: Work in progress
Better knowledge about the model: Routine documentation How-to-run manuals How-to-make-graphics (in GrADS) manuals
Improved input data: Data mining GIS-helped soil data

Forthcoming work / cooperation
Tool for discovering/studying potential “wind farms” sites
Campaign of measurements in Temuco, University of Stockholm (mar-jul 2005)
Better residential emissions inventory/estimations
