YOGYAKARTA Do you know what SADEWA BRIN is? This is a satellite-based disaster early warning information system developed by the Center for Climate and Atmospheric Research National Research and Innovation Agency (BRIN) to support R&D activities and its applications by related operational agencies.

More information about the BRIN SADEWA application can be seen in the following reviews:

SADEWA is an acronym for the Satellite-based Disaster Early Warning System.

Quoted from the official BRIN website, SADEWA is a disaster early warning information system related to extreme atmospheric conditions supported by remote sensing satellites and atmospheric dynamics models.

Researcher of the BRIN Climate and Atmospheric Research Center, Anis Purwaningsih explained, the development of the SADEWA application aims to provide parties related to disaster management at both the central and regional government levels in the context of managing the risk of hydrometeorological disasters.

"SADEWA is a web-based application consisting of a Himawari-8 satellite-based atmospheric monitoring system, a Weather Research Forecasting (WRF) model-based atmospheric prediction system, and an extreme rain early warning system," said Anis, driven by VOI, Friday, December 30, 2022.

How the BRIN SADEWA application Works

Anis explained that the way the SADEWA application works is to monitor atmospheric conditions in real time, predict the possibility of extreme rain, and provide early warning information to parties related to disaster management.

"SADEWA presents atmospheric parameter information such as rainfall, wind, clouds, temperature, humidity, and others," he said.

The SADEWA BRIN system predicts the possibility of potential disasters using computer models, and conveys disaster early warning information via display monitors in a control room.

Development of BRIN SADEWA Application

For information, the SADEWA 1.0 application began to be developed in 2010 as a pilot project for the West Java region which is prone to various disasters such as floods and landslides. Furthermore, the system has now been developed into the Sardehan 6.0 for Indonesian territory.

SADEWA covers the entire territory of Indonesia with a spatial resolution of 5 kilometers, a time resolution of 1 hour, with a prediction reach of the next 3 days. Sadives with a higher resolution (1 kilometer) are available for the West Java region with the same time resolution and prediction range as SADEWA 5 kilometers," continued Anis

Information Accessible Through the BRIN SADEWA Application

Anis continued, information accessible through SADEWA includes Cloud Peak Temperature, Water Steam, Visible, Near Infrared, Growing Clouds, Inter-tropic Convergence Zone (ITCZ), Monsun Index, IOD, MJO, SOI, ONI, AWS and Radar.

As for the prediction for the next three days, users can access information related to Clouds, Rain, Surface Temperature, Pressure, Water Steam, 10 meters Wind, 850 millibar wind, and 200 millibar wind. SADEWA can also provide early warnings of extreme rain.

"People can access SADEWA via, Sadawa.brin.go.id link for a resolution of 5 kilometers, while sadewa.brin.go.id/sadewabgr for a resolution of 1 kilometer," explained Anis.

BRIN SADEWWA Application Feature

The SADEWA application has several weather information features such as rain, IR1, IR2, IR1-IR2, IR1-IR3, COM, and others. Of the many choices, some of the most important features include Rain, IR1-IR2, IR1-IR3, and COM.

If you choose information about rain, you will see Indonesian territory and cloud cover.

Maps can be enlarged to see a more specific location. You will see areas with black to gray cloud cover. The area covered by clouds has the potential to experience rain from light to heavy intensity.

The IR1-IR2 feature can notify areas covered by Cirrus clouds (thins) or Cumulonimbus clouds.

Areas covered by dark green Cumulonimbus clouds mean they have the opportunity to rain.

While the IR1-IR3 feature can notify users about areas covered by high clouds (Cumulonimbus) that are dark blue and low clouds (Culus).

Just like the previous choice, if an area is covered by Cumulonimbus clouds, the region has the potential to experience heavy rain.

BRIN SADEWWA Application Function

The BRIN SADEWA application can be used to predict weather, obtain more accurate data, and cross-check other pages that have similar functions, such as those of the Meteorology, Kilmatology and Geophysics Agency (BMKG).

In addition, the SADEWA application also functions as a tool for disseminating information from data obtained by BRIN. Even so, the interpretation of information and data remains the domain of BMKG as the authority regarding weather information in Indonesia.

That's the information about what SADEWA BRIN IS. May it be useful!
