Total rainfall in May 2012 = mm 204 (UNESCO Rainfall Station - 6.230830°S, 106.803914°E, el. ~ 30 m a.s.l)

May average: mm 160 (1984-2009 - Halim station, BMKG)
May Max: mm 282 (May 1984 - Halim station, BMKG)
May Min: mm 30 (May 1996 - Halim station, BMKG)
The average rainfall for the month of May (period 1984-2009) for Halim Station (5 km East of UNESCO Office) is then mm 160.
May 2012 rainfall (204 mm) is higher than the 26 years rainfall average for May (160 mm) and 35% of May 2012 rain (mm 71) occurred in just 2 days, in particular mm 27 on 30 May (2 hours) and 44 mm on 31 May (2 hours 15 minutes).
The graphs below show the average monthly rainfall for Halim PK station (BMKG) for the period 1984-2009 and the current 2012 rain in UNESCO rainfall station.

As a contribution to Climate Change and Variability data on precipitation, since February 2007 a rainfall station (manual pluviometer) is operational in UNESCO Jakarta Office. The parameters acquired by the station are P in mm, T in °C, EC in μS/cm, TSD in mg/l, salinity in g/l and pH. Besides the above parameters obtained on each single event, isotopes analyses for monthly samples were analysed from February 2007 to April 2011 and daily samples analysed from September 2009 to November 2010.This
station is also operating as a contribution to the HARIMAU Project (Hydrometeorological ARray for ISV-Monsoon AUtomonitoring) by Japan EOS Promotion Program (JEPP) and implemented by JAMSTEC (Japan Agency for Marine-Earth Science and Technology), and Indonesian partners BPPT (Agency for the Assessment and Application of Technology), BMKG (Agency for Meteorology and Geophysics) and LAPAN (National Institute of Aeronautics and space). From September 2007 daily events are collected for JAMSTEC which is performing stable isotopes (18-O and 2-H) analyses on rain water from the South China Sea.
