Abstract

Many studies have shown the relationship between meteorological elements and air quality. However, some aspects of the relationship are unknown, particularly in Indonesia, which has a variety of topographical landscapes and climatic conditions. This study seeks to define the relationship between meteorological variables and the diurnal pattern of three pollutants that contributes to the so-called Indeks Standard Pencemar Udara (ISPU), similar to the Air Quality Index (AQI), in a remote area in Bukit Kototabang, West Sumatra, Indonesia. The three parameters, namely Particulate Matter 10 micrometers (PM10), carbon monoxide (CO), and tropospheric ozone (O3), were correlated with diurnal variations in temperature and relative humidity in the months of maximum rainfall and minimum rainfall in 2020. The T-test was used to obtain each parameter's mean and variance sizes and the significant differences among the parameters. The results showed that PM10 has a significant distribution when high and low rainfall, but no significant relationship exists between temperature and relative humidity. Carbon monoxide has significant fluctuations to differences in rainfall and diurnal variations in air temperature. Meanwhile, O3 shows a weak correlation to the rainfall variation but has a high correlation to diurnal variations in the temperature and relative humidity. The results suggest that air temperature can significantly affect the diurnal concentration of pollutants, which involves photochemical reactions in their formation, such as ozone and carbon monoxide. It also shows the potential for worse air quality during the low rainfall. As the pollutant level can be higher during the dry season compared to the rainy season, efforts to reduce the pollutant emission during the dry season, like forest and land fires, need to gain more attention.

Abstract

GBON is a global network system that provides weather data for weather forecasters and climate experts worldwide. However, there are still developing countries, such as Timor-Leste, that have yet to meet the GBON requirements. This paper delves into the gap between the current conditions at DNMG, an institution that provides meteorology, climatology, and geophysics services in Timor-Leste, and the conditions required to comply with GBON requirements in terms of organizational governance, observation infrastructure, and human resource capacity. The study used a qualitative method with a descriptive approach, and data was obtained from interviews with key figures involved in the Systematic Observation Financing Facility framework. The analysis reveals that the DNMG organization's position as a technical directorate in the Ministry of Transport and Communications of Timor-Leste limits its authority in budget planning and organizational development. Despite meeting the horizontal resolution of the basic surface observation requirements for Timor-Leste as a Small Island Developing States (500 km), the poor condition of the equipment and the failure to exchange data internationally prevent Timor-Leste from complying with GBON. Furthermore, limited number and capacity of human resources and the absence of Standard Operating Procedures hinder effective work processes within DNMG. To increase the capacity of DNMG human resources, BMKG actively provides assistance and support to DNMG Timor-Leste in the form of training activities and workshops to meet the observation and service standards required in GBON. Keywords: GBON, gap analysis, organizational governance, observation infrastructure, human resources
