The History of Satellite Applications Training at IMTR-Nairobi

Weather analysis relies heavily on the availability of accurate observation data. For meteorologists to draw meaningful conclusions, they must be well-trained in various meteorological data types and be proficient in using diverse data-processing methods. In Africa, there has long been a pressing need to develop a critical mass of skilled meteorologists capable of analyzing and interpreting weather data at a level comparable to that of developed countries. To meet this demand, capacity development in Satellite applications has become a central objective for meteorological personnel across the African continent.

However, the challenge of training in satellite data processing has been significant. Many African countries lack the necessary infrastructure, equipment, and resources to provide this specialized training or to apply satellite data effectively across various sectors of economic development.

To address this gap, international cooperation and bilateral agreements have played a crucial role. Organizations such as the U.S. National Oceanic and Atmospheric Administration (NOAA), the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), and the World Meteorological Organization (WMO) partnered with IMTR to offer sponsored satellite applications training at Regional Training Centres across Africa. Due to technological limitations, these training sessions were initially conducted face-to-face, with countries sending one or two representatives at a time to attend workshops and training courses.

In 1987-1989, the University Corporation for Atmospheric Research (UCAR)—a consortium of universities focused on atmospheric research—established the Meteorological Education and Training (COMET) division. IMTR-Nairobi was identified as a key partner, receiving training materials on compact discs (CDs) with a diameter of 30 cm, similar to vinyl records. This early technology, however, was not sustainable due to limited production, unreliable hardware, and the inadequate computing power at IMTR at the time.

With the introduction of Windows 95 in 1993, IMTR was able to upgrade its systems and begin training on Windows-based applications. This upgrade also allowed the National Meteorological Center in Nairobi to use a French weather processing system called Synergie, which enabled access to satellite data from the Meteosat satellite. The Meteosat data provided critical information across three channels: visible, water vapor, and infrared.

In 1997, the African Satellite Meteorology Education and Training (ASMET) project was launched collaboratively by EUMETSAT, WMO, and COMET. The initiative aimed to improve the accessibility of satellite data and enhance the capacity to process, analyze, and apply this data in weather forecasting. By improving the quality of forecasts across Africa, the ASMET project became a pivotal part of the continent's meteorological development. The project produced training materials in CD format and online, addressing the significant data gaps that existed due to limited ground-based observations in many African countries.

The ASMET project began by training trainers, which allowed for the development of specialized training materials on topics such as: The Fundamental Principles of Remote Sensing, Understanding Indian Ocean Tropical Cyclones, Continental Droughts and Floods, The Development of Easterly Waves and Their Effects on Squall Lines in West Africa, Nowcasting Using Satellite Data etc.

By 2010, with support and in collaboration with EUMETSAT, IMTR-Nairobi was able to offer both face-to-face and virtual training courses in Satellite application. As internet access became more widespread across Africa, this online training approach helped accommodate more than 80 participants simultaneously, overcoming the financial and logistical challenges that had limited face-to-face participation.

Between 1998 and 2024, more than 15 satellite training modules have been developed, all of which are available on the ASMET website.

At IMTR-Nairobi, we conduct courses that integrate satellite meteorology with practical applications. Our ASMET and PUMA laboratories are equipped with the necessary hardware and software for receiving and analyzing and visualising satellite data.

The ASMET, the African Satellite Meteorology Education and Training project is supported by meteorology instructors from the:

  • South African Weather Service (South Africa)
  • Institute for Meteorological Training and Research (Kenya)
  • EAMAC/ASECNA (Niger)
  • Morocco National Meteorology Department or DNM (Morocco)
  • EUMETSAT (Germany) and
  • The COMET® Program (USA).

ASMET Group together with CEO and Training Manager of South African Weather Service.
The ASMET (African Satellite Meteorology Education and Training) project produces free, self-paced online learning resources that train African forecasters how to enhance their forecasts by making better use of meteorological satellite images and products. The lessons are published on the ASMET website and can also be accessed through the MetEd website. The lessons are completely free for Forecasters to use. Registration on the MetEd site is required to gain free access to the resources. The lessons, which are both in English  and French, are produced by the ASMET team and are self-directed online learning resources that are meant to be used by forecasters, meteorologists and researchers at their own pace and address various common weather phenomena that African countries experience.
 
In this way, learners not only enhance their knowledge on the various meteorological phenomena but they also become aware and acquire knowledge on the use and interpretation of meteorological images and products. These lessons have been published and used by African Forecasters for over 20 years and thus pose as a vast resource pull where forecasters from NMHSs can refer to  learn and also improve on their skills. The data used for the lessons include Satellite data and derived products from EUMETSAT Geostationary satellites and Numerical Weather Prediction model data. Africa relies on these data sets to develop and setup a Nowcasting system where initiation,  rapid development, evolution and movement of synoptic and mesoscale weather systems can be monitored at a spatial and temporal scale. Therefore, forecasters require training to ensure they possess the required forecasting skills and  are competent during the nowcasting process. 
 
Low cost training; In addition to not having  to  leave the forecasting office to learn, the only equipment and resources that a  forecaster requires is a reliable internet connection and a computer to access these free lessons to build on his competency. 
The forecaster will improve his knowledge and skills on:
  • Interpretation of significant meteorological phenomena by use  of conceptual models.
  • Use of NWP products and be aware of the strengths and weaknesses of NWP products.
  • Verification of forecast products against observations, measurements and meteorological satellites products.
  • The use of meteorological satellite data including RGBs and how to interpret them and apply them in analysis of various synoptic and mesoscale weather phenomena. 
  • Blending meteorological satellite data and products with NWP products in  the Nowcasting process.
The case studies used are based on significant weather/extreme weather cases experienced such as thunderstorms, Fog, Dust Tropical Cyclones etc which cause devastating effects in the areas affected. The lessons take the learner through the forecasting process step by step highlighting the data to use and the significant thresholds to look for that could trigger dangerous hazards and pose a risk to the communities. A forecaster applies such knowledge and forecasting skill in his operational duties of nowcasting and producing short range forecasts or issue warnings and advisories. ASMET Lessons are always updated regularly based on the needs of the users in the African region. They can be shared with colleagues and other learning institutions to build capacity in the use of meteorological satellites, data and products.
