What Tahmo_world does

TAHMO (Trans-African Hydro-Meteorological Observatory) develops and operates a distributed network of automated hydro-meteorological monitoring stations across Africa and provides climate data, analytics, and related software services. Founded as a partnership between Delft University of Technology and Oregon State University, the company has deployed 800+ stations across more than 20 African countries. Each station uses ATMOS 41 all-in-one weather sensors paired with ZL6 and EM60G data loggers from METER Group, recording 12 environmental variables at five-minute intervals and transmitting data hourly over GPRS. Operational headquarters are co-located with the Kenya Meteorological Department in Nairobi, with the corporate entity registered in Delft, Netherlands.

The product portfolio spans four layers: (1) the weather station hardware itself, (2) a cloud-based online data portal providing cleaned, analysis-ready precipitation datasets used for satellite validation, forecast skill evaluation, and rainfall research, (3) a Field Maintenance Checklist mobile application for field technicians, and (4) custom Dashboard & Software Development services that convert environmental data into decision-support products. A School-2-School programme layers in teaching materials for K-12 education. Primary customers are National Meteorological and Hydrological Services (NMHSs), educational institutions, and academic research organizations.

TAHMO generates revenue through three streams: hardware sales of weather stations, data access and monetization through its online portal, and professional services covering station installation, maintenance, and ongoing operations. A significant share of operating capital is sourced from institutional grants and development funding (Horizon 2020, USAID, World Bank, WMO, NOAA via TomorrowNow, NWO, the Gates Foundation, and the Global Resilience Partnership). The company also benefits from in-kind technology partnerships with IBM (supercomputing for rainfall modelling), Meteoblue (forecasting), METER Group (sensors), Rhiza Research, and the GSMA. The go-to-market motion is primarily direct-to-institution via the website and data portal, supplemented by co-development relationships with national meteorological agencies acting as channel partners across the continent.

Core offering

TAHMO operates a continental-scale network of automated hydro-meteorological weather stations across Africa, providing climate, water, and weather data through online services. The company designs and sells weather stations, installs and maintains them, and develops custom dashboards and software solutions for governments, researchers, and educational institutions. With 800+ stations deployed across 20+ African countries and plans to scale to 20,000 stations, TAHMO addresses the critical shortage of reliable ground-truth weather data on the African continent.

Product overview

TAHMO (Trans-African Hydro-Meteorological Observatory) operates a distributed network of automated weather stations across Africa, offering climate data services, station installation/maintenance support, and custom software solutions. The core offering consists of the TAHMO weather station network, complemented by an online climate data portal, mobile maintenance applications, and educational teaching materials. The company works with National Meteorological and Hydrological Services (NMHSs) to deliver water, weather, and climate services for early warning systems.

Direct peers

• Campbell Scientific: Designs and manufactures rugged weather stations and environmental data loggers used in scientific and government monitoring networks worldwide. Comparable product offering (automated weather stations with remote telemetry) to TAHMO's deployed network.
• aWhere: Provides agricultural weather data and analytics, particularly for developing-country markets. Closely comparable to TAHMO in combining weather-station-derived data with downstream decision-support analytics for agriculture and food security.
• METER Group: Supplies the ATMOS 41 sensors and ZL6/EM60G data loggers that form the core of every TAHMO station. As TAHMO's hardware partner, METER operates in the same environmental-monitoring technology space and sells comparable weather-station solutions globally.
• Ignitia: Specializes in tropical weather forecasting for West Africa, delivering highly localized forecasts via SMS to farmers. Comparable target market (African agriculture) and similar problem of building weather intelligence where infrastructure is sparse.

Emerging players

• Climavision: Weather radar and forecasting company focused on filling observation gaps, particularly in data-sparse regions. Conceptually comparable to TAHMO in addressing the 'infrastructure gap' problem, though using radar rather than ground stations.

Broad incumbents

• DTN: Provides weather, climate, and agricultural data services to industries globally. Comparable business model combining observational data with operational decision-support, particularly in agriculture where TAHMO also plays.
• Vaisala: Global leader in professional weather instruments and observation networks, including systems used by national meteorological services. A larger incumbent competing in the same ground-based observation infrastructure space that TAHMO addresses.
• Tomorrow.io: Weather intelligence platform combining forecasts, observations, and decision APIs for enterprise customers. A broader, commercial-scale weather data platform that overlaps with TAHMO's data-services ambitions but at a much larger scope.
• AccuWeather: Major commercial weather data and forecasting provider with global reach. A broad incumbent in the same weather-information category, though primarily serving consumer/enterprise forecasting rather than ground-station infrastructure in Africa.
• IBM (The Weather Company): IBM is both TAHMO's technical partner (supercomputing for rainfall modelling) and a global weather-data incumbent via The Weather Company. Operates at vastly larger scale but in the same weather-data and forecasting category.
