  6. Synoptic Meteorology Synoptic Meteorology Summary • Standard meteorology parameters recorded • [Dry and Wet Bulb Temperature, Pressure, Wind Speed and Direction, Rainfall, Visibility, Cloud type and amount] • Why? • To supply a snapshot of the current weather situation, for forecast purposes • Climate record purposes

  8. Upper Air

  9. Upper Air

  10. Upper Air 10th Oct 2008

  11. James Reilly & Valentia Observatory

  12. Upper Air Upper Air Summary • Valentia is the only place in the Republic of Ireland that launches upper air balloons for meteorological purposes • 4 accents a day • Why? • To supply vertical profile data to forecast models • Used to calibrate satellite sensors • Provide Tephigram chart as a forecast analysis tool

  13. Air and Rainwater Pollution Monitoring • Air Monitoring: • EMEP:NO2- (Nitrogen Dioxide) – daily measurements • EMEP:SO2- and SO4- (Sulphur Dioxide) • – using impregnated filters – daily measurements 2. Rainwater Sampling: EMEP :Na+, Ca+, K+, Mg+, NH4-N, Cl-, NO3-N, SO4-S, Conductivity– daily IAEA: Analysis – monthly EPA: Heavy metals – monthly pH: Daily

  14. Air and Rainwater Pollution Monitoring NO2 Pollution levels in Europe (Jan 03 – Jun 04)

  15. Annual average SO2 levels for the period 1980 to 2002 at Valentia Air and Rainwater Pollution Monitoring • SO2 and SO4 since 1981 – most extensive record in Ireland. • NO2 since 1989 – most extensive in Ireland From Bashir and McGovern 2004 Steve Smith - Pacific Northwest National Laboratory

  16. Air and Rainwater Pollution Monitoring Air & Rainwater Monitoring Summary • Valentia’s lab (& HQ Dublin lab) measures pollutants in Air and Rainwater • Why? • To provide excellent background count values for Europe • Monitor changes in pollution levels over Ireland

  17. Phenology Phenology: the study of biological phase changes in Plants and Animals Observed Phases at Valentia: Beginning of leaf-unfolding General flowering First ripe fruits Autumn coloring Beginning of flowering Leaf fall IPG & COST 725 A B C D E F G H I Photo: EevaKotilainen.

  18. Length of Growing Season at Valentia Observatory Phenology Adapted from Donnelly, Salamin and Jones 2005 • Phenology used as indicator for climate change • Most species now leaf earlier than in 1970 • An increase in 1oC average Spring temperature corresponds to an approx 7 day advance of the beginning of growing season

  19. Phenology IPCC 4th Assessment Report - 2007 Working Group II Report "Impacts, Adaptation and Vulnerability Chapter 1: Assessment of Observed Changes and Responses in Natural and Managed Systems - Page 113

  20. Phenology Phenology Summary • Valentia Observatory records phase changes on a number of ‘cloned’ trees • Why? • Phenology can by used as a climate change indicator

  21. Solar Radiation Measurements

  22. Solar Radiation Measurements

  23. Solar Radiation Measurements Malin Head Belmullet Clones Dublin Airport Birr Valentia Irish Primary Solar Radiation Network Irish TUCSON Solar Radiation Network

  24. Solar Radiation Measurements Solar / Terrestrial Radiation Summary • Valentia Observatory records ‘Direct’ ,‘Diffuse’ and ‘Global’ solar radiation • Calibrate Ireland’s Solar radiation network • Why? • Climate Records • Research

  25.
