  1. THE NAME SIMPLE RAINGAUGE NETWORK IN MEXICO To develop an improved daily gauge-only precipitation analysis products for México in support for NAME as well as several other ongoing PACS and GAPP projects. Specifically, we will develop and provide high-resolution improved daily precipitation analyses for México. For this effort, enhancements to the network of simple raingauges will be installed over Northwest and Northcentral Mexico.

  2. NAME Needs for Additional Precipitation Observations There are large portions of the core and peripheral monsoon regions (e.g. North Central Mexico) where the network is sparse.

  3. Gridded daily analysis Merged Real Time Precip. (2001-present) Historical reanalysis Mexico (1948-2000) daily http://www.cpc.ncep.noaa.gov/products/precip/realtime/index.html

Atmospheric interactions with land surface using mesoscale NWP models. Surface and local atmospheric circulations play an important role in the development of convection, Yet very few models properly represent the land surface atmospheric interactions. There have been serious problems obtaining sufficient validation data.

  6. Current Status of the Raingauge Network in Mexico It was agreed in previous meetings that future modeling and diagnostic work related to the warm season precip. requieres additional raingauge data. The Mexican Climatological Network has been in a state of decay in recent years. Today there are less than 2000 stations that cover the entire country, major limitations are budgetary, and there are clear indications that the network will continue to deteriorate.

  7. This project has the objective of installing a relatively large number (1600) of simple raingauges over several data sparse regions of Northwest and North Central Mexico to complement other data sets that will be gathered during NAME. It also promotes the idea that the network can be improved via cooperation between the institutions involved and the general public. The activity will serve to educate the public, especially rural agricultural and industrial groups with interests in climatology.

  8. Specific Objectives • Implement an enhanced network of simple raingauges in Northwest and North Central Mexico. • a) Select and instruct cooperative observers. • ranches, schools, health clinics, public facilities, etc. • b) Install simple raingauges. • a Cooperative Rainfall Observers Network will installed.

  9. Specific Objectives • Establish data collection procedures. • a) collect data in a monthly basis • b) digitize data and perform preliminary quality control. • c) Compute monthly and seasonal totals at each station location. • d) develop a WEB Accesible Database • e) collect original data cards at the end of the 2003 and 2004 monsoon seasons.

  10. Specific Objectives • Provide improved high-resolution daily precipitation analyses for Mexico (and US-Mexico merge). • a) Incorporate new data into CPC’s historical daily Mexican precipitation database. • b) produce improved high resolution gridded daily analyses for Mexico. • c) Satisfy GAPP requirements • d) diseminate precipitation analyses

  11. Specific Objectives • Disseminate the daily analyses via the established data distribution centers. • WEB accesible data base • regular mail • by telephone

  12. Specific Objectives • Evaluate the quality of the new analyses via comparative and diagnostic studies. • a) asess the impact of the new data on analysis quality. • b) exploit daily analyses in other NAME-related activities. • Diagnostic studies of relationships between moisture transport and precipitation during NAM. Selective response of precipitation to temporally and spatially varying forcing of snow and soil moisture. Coupling a dynamic L-S model into MM5.

  13. Relevance and Benefits Our proposed activities are directly responsive to NAME contributions. The precipitation products will provide rainfall measurements that will be used to asess the climatic effects of fluctuations in the North American Monsoon. The scientific community and the general public (e.g. cooperative observers) will also benefit from the proposed work in that science education is an integral part of this activity.
