EXTREME VALUE CHARACTERISTICS OF PM2.5 WITH INFLUENCING METEOROLOGICAL VARIABLES IN EAST JAKARTA (CASE STUDY: JUNE - AUGUST 2022)
The annual concentration of PM2.5 in Jakarta is four to five times the WHO air quality guidelines. This poor air quality affects the health of the people as well as the environment. There were about 5.5 million people associated with air pollutionrelated diseases in Jakarta in 2010 or about 11 ca...

| Summary: | The annual concentration of PM2.5 in Jakarta is four to five times the WHO air
quality guidelines. This poor air quality affects the health of the people as well as
the environment. There were about 5.5 million people associated with air pollutionrelated
diseases in Jakarta in 2010 or about 11 cases per minute with medical costs
of Rp60.8 trillion in 2022. Quoted from the results of the final report on air quality
monitoring activities in DKI Jakarta in 2021, daily data on high concentrations of
PM2.5 have a percentage above 80% in SPKUA 4, Lubang Buaya, East Jakarta.
The interaction between PM2.5 and meteorological factors plays an important role
in air pollution analysis (Yang et al., 2017).
The purpose of this study is to understand the characteristics of PM2.5 extreme
values with meteorological variables that affect them in East Jakarta from June to
August 2022. PM2.5 observation data was obtained from PT Nafas Indonesia at
Condet station, East Jakarta. The meteorological variables considered are
atmospheric stability represented by potential temperature, wind speed, and
rainfall. The CDF (Cumulative Distribution Function) value is used to obtain the
extreme high and low concentration of PM2.5.
The characteristics of extreme conditions are indicated by concentration values that
are greater than the seasonal average, and there are differences in diurnal patterns
in both, namely in the extreme case the peak concentration of PM2.5 occurs in the
morning and evening, while in the seasonal average it peaks from night to the
morning. Suring high extreme cases, atmospheric stability conditions tend to be
unstable, indicated by a larger d?/dp value than during low extremes. Wind speed
during the high extreme case is lower than the low extreme case. Also, there is no
rain event during the high extreme case and there is rain in the low extreme case. |
