RIMES Strengthens Timor-Leste’s Early Warning Capability Through Intensive Capacity-Building Program

RIMES conducted a rigorous three-week technical capacity-building program for Timor-Leste at its headquarters in Pathum Thani, Thailand, from 27 April to 15 May 2026, under the Green Climate Fund-United Nations Environment Programme (GCF-UNEP) project “Enhancing Early Warning Systems to build greater resilience to hydro-meteorological hazards in Timor-Leste (FP171)”. Aligned with the training architecture established by RIMES Director General, Mr. A.R. Subbiah, the program’s overarching objective was to transition Timor-Leste’s Direção Nacional de Meteorologia e Geofísica (DNMG) from general weather forecasting to operational multi-sector Impact-Based Forecasting (IBF).

Weeks 1 & 2: S2S Forecasting and WRF Configuration 

During the first two weeks, RIMES equipped DNMG meteorologists with the computational skills required to configure and run high-resolution Weather Research and Forecasting (WRF) simulations for 15-day (sub-seasonal) to 3-month (seasonal) horizons. Participants engaged in extensive command-line operations, utilizing Linux, Python, and Climate Data Operators (CDO) to process Global Climate Model (GCM) data, specifically downloading and subsetting GFS and ECMWF datasets.

Technical instruction covered the complete WRF architecture, including the execution of WRF Preprocessing System (WPS) components: geogrid, ungrib, and metgrid. The sessions concluded in converting GRIB files to NetCDF formats, applying bias correction using historical station data, and utilizing GrADS and GIS tools for spatial visualization to prepare localized seasonal outlooks for the 11th Monsoon Forum.

Week 3: Operationalizing Multi-Sector IBF and Decision Support Systems 

In the final week, RIMES expanded the program to 12 delegates representing critical institutions, including DNMG, the Civil Protection Authority (APC), National Maritime Authority (AMN), Ministry of Health, APORTIL, Ministry of Agriculture, and the Maritime Police. This phase focused on integrating the generated WRF outputs into sector-specific Decision Support Systems (DSS) to translate hydro-meteorological thresholds into actionable operational triggers across key sectors: 

  • Agriculture: Utilizing CDIS for rainfall variation tracking and SESAME for long-lead agrometeorological advisories.
  • Disaster Risk Reduction (DRR): Employing DRR DSS for high-resolution disaster risk mapping and spatial vulnerability analysis.
  • Ocean and Fisheries: Leveraging OSFAS for interpreting wave height, wind, and sea state forecasts.
  • Health: Utilizing the Climate Risk Information System for Health (CRISH) for predictive disease modeling based on S2S trends.

Simulation and SOP Validation

To stress-test multi-timescale integration, delegates executed a cascading hazard simulation, responding to a prolonged El Niño-induced drought interrupted by a sudden high-impact cyclone event. This exercise mapped slow-onset impacts to real-time disaster response workflows across sectors. The multi-agency delegation subsequently validated and formalized a unified Standard Operating Procedure (SOP), establishing clear institutional mandates for DSS management, early warning dissemination workflows, and data-sharing protocols, a significant milestone in strengthening Timor-Leste’s preparedness for hydro-meteorological hazards.

The successful completion of this program represents a concrete leap forward in Timor-Leste’s early warning capability. With a validated multi-agency SOP, operational DSS tools across key sectors, and a delegation ready to deliver impact-based forecasts at the 11th Monsoon Forum, Timor-Leste is now better positioned than ever to protect lives and livelihoods in the face of hydro-meteorological hazards.
