  • Climate change has become an issue that needs attention, as it has significant impacts and risks, especially on the sustainability of living beings and future generations. Therefore, continuous monitoring is necessary to enable mitigation efforts before it affects the surrounding environment.

  • By developing this program, BMKG can also adopt and integrate advanced technologies such as climate monitoring through sensors, big data analysis, and increasingly accurate and sophisticated weather prediction systems.

  • Data and information collected through the Agroclimate and Weather Station program can also be used for further research in the fields of meteorology, climatology, and agriculture. Additionally, this data can serve as a basis for the development of more effective policies in natural resource and environmental management.

Automatic Agroclimate and Weather Station

Programs AAWS/EWS

AAWS (Automatic Agroclimate and Weather Station) program has been developed by BMKG to automatically monitor weather and climate elements, with the aim of directing its utilization towards the agricultural sector. This automatic agroclimate observation equipment generates agroclimate data at the location and its vicinity, with its management being carried out in collaboration with other institutions from the agricultural sector.
Legal Basis:
  • Standard Operational Procedures (SOP) Number: SOP/26/KPNK/I/2019. see details

AAWS/EWS consists of several main parts : 
1.Data Collecting
The sensors on the AAWS device will measure various weather and agroclimate parameters. Data from these sensors will then be stored on a data logger.

2.Data Transmission to the Server
The data recorded on the data logger will be processed and formatted appropriately. Once processed, this data will be automatically transmitted to the server via an internet connection.

3.Data Analysis and Processing
On the server, the received data will undergo further processing to generate useful and comprehensible information for users. Weather and agroclimate data can be processed into graphs, tables, or other visual information that is easy to understand.

4.Data Presentation
Users can access this data through the provided dashboard. This dashboard can be accessed either via smartphones or PCs using the provided application or website. By accessing the AAWS dashboard, users can view real-time weather and agroclimate information. The presented data includes current weather conditions, daily weather patterns, and agroclimate trends over specific periods.
