Central Java have 39 Agriculture and 6 BMKG’s Stations, but from all of them we only 4 stations that have good data series. They are Borobudur Agriculture Meteorologi Station, Cilacap Meteorological Station, Tegal Meteorological Station and Semarang Climatological Station

39 Station Agriculture Meteorological Station

6 BMKG’s stations in Central Java

4 stations that have good data series

From 4 stations that have good data series, only 3 stations that have daily dataset. The station are Cilacap Meteorological Station, Semarang Climatological Station and Tegal Meteorological Station. The Borobudur Agriculture Station only have monthly dataset.

To Obtain te Cilmate Indice, we do :

Collecting Dataset Check the Quality Control Check the homogeneity Calculation Indice and trend

Data Quality Control :

The data must have some criteria :• Precipitation >= 0 mm• TMax > TMin

The homogeneity of precipitation data series for all of station are good

The homogeneity of maximum temperature for 3 station are not good

except Semarang Climatological Station is good.

The homogeneity of minimum temperature for Cilacap and

Tegal Meteorological Station are good but for Borobudur Agriculture

Meteorological Station and Semarang Climatological Station are not

good.

Trend of precipitation for all of station are decrease, but

Trend of maximum and minimum temperature for all station are

increase.
