"Human activities have resulted in (the emission of) CO2 and other greenhouse gases. This IG3IS tower will generate data that can be calculated to monitor GHG trends," BMKG Head Dwikorita Karnawati remarked at the tower inauguration commemorating the 73rd World Meteorological Day in Bukit Kototabang, West Sumatra, on Monday.
During the event held at the global atmosphere watch (GAW) station in Bukit Kototabang, Karnawati affirmed that the BMKG was planning to build similar towers in regions across Indonesia in order to detect areas producing the most greenhouse gases.
The BMKG head reminded that climate change had increased the frequency of occurrence of natural disasters.
The National Disaster Mitigation Agency (BNPB) reported that 95 percent of all disasters in Indonesia are hydrometeorological in nature.
"President Joko Widodo has voiced sternly that climate change is feared by all countries and not just in Indonesia," she remarked.

The BMKG head pointed out that climate change had increased the frequency and intensity of hydrometeorological disasters in Indonesia.
"Before 1980, the El Nino and La Nina re-occurrence interval was 5-7 years, but from 1981 until now, they are increasingly frequent (to the extent) that they recur every two to three years, and this is a climate change impact," she elaborated.
Head of the Applied Climate Information Service Center Ardhasena Sopaheluwakan remarked that the new 100-meter tower has meteorological sensors that can monitor GHG concentrations at three altitude points: 30 meters, 70 meters, and 100 meters.
With those sensors, the tower can provide characteristics of GHG at different heights that contribute to the IG3IS program.
"Increasing the GHG monitoring capacity through IG3IS will be used further in developing a modeling for GHG emissions as complementary information for the national GHG inventory," he remarked.
The GHG national inventory will be used for the global stocktake estimate that is part of the Paris Agreement goals by 2030.
