Chile

Rodrigo Delgado UrzúaUniversidad de La Frontera

Temuco, Chilerdelgado@netexpress.cl

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
