  1. EANET Monitoring Data for The Model Intercomparison Study Kazuhide Matsuda Acid Deposition and Oxidant Research Center (ADORC)

  2. Introduction • The preparatory phase of Acid deposition monitoring network in East Asia (EANET) was carried out successfully. • “Report on the Acid Deposition Monitoring of EANET during the preparatory phase” was published in August 2000 with the monitoring data. • After the preparatory phase, the regular phase was started from January 2001.

  3. EANET sites in 2000

  4. Classifications of EANET sites • The data monitored in remote sites and some rural sites are suitable for validations of regional scale transport models. • The year 2000 • Remote: 16 sites • Rural: 8 sites • Urban: 14 sites

  5. Remote sites Thana Rata, Malaysia Tarelj, Mongolia Cheju, Korea

  6. Rural sites Serpong, Indonesia Los Banos, Philippines Patumthani, Thailand

  7. Available monitoring data • The preparatory phase -open to public • Monthly averaged data (Apr.1998 ~ Dec.1999) • A lot of lack of data • The monitoring data in 2000 • The data set in 2000 is relatively complete. • The issue of data disclosure in the regular phase will be discussed in the 3nd Intergovernmental Meeting held in November 2001.

  8. Quality of monitoring data for wet deposition (1) • Ion balance check (R1) • Conductivity balance check (R2)

  9. Quality of monitoring data for wet deposition (1) • Inter-laboratory comparison project • Round robin analysis survey of uniformly prepared artificial rainwater samples SO42- (2nd Survey)

  10. NO3- (2nd Survey) • NH4+ (2nd Survey)

  11. Applied methods for air quality monitoring in 2000 • Automatic monitoring method • UVF (SO2) , CLD (NO, NO2) UV photometric (O3), TEOM, b-ray (PM) etc. • China, Indonesia, Japan, Thailand • Filter pack method • 4-stage filter pack method • Malaysia, Mongolia, Philippines, Russia, Vietnam

  12. Items of air quality monitoring in 2000

  13. Results of the monitoring in 2000 • SO2 concentration (monthly average) • Urban • China 2, Japan 1, Mongolia 1, Philippines 1 , Thailand 2, Vietnam 1 • Rural • China 1, Indonesia 1, Japan 1, Philippines 1, Thailand 1, Vietnam 1 • Remote • Japan 8, Malaysia 1, Mongolia 1, Russia 1, Thailand 1 1 ~ 100 ppb 1 ~ 10 ppb < 1 ppb

  14. A topic of the year 2000 • Extremely high concentration influenced by volcanic SO2 from Miyake Island volcano 12 ~ 24 September 2000

  15. Rishiri Tappi Sado Oki Happo Banryu Ijira Miyake Island volcano Yusuhara

  16. Summery • Availability of EANET monitoring data • 1998~1999 (opened) • 2000 (not opened yet) • Quality of the wet deposition monitoring data • Air quality monitoring • Automatic monitors and filter packs • A topic of the year 2000 • Eruption of Miyake Island volcano
