#SDGAction52070
Description
The objective is to produce timely and accurate rainfall maps for ten countries in sub-Saharan Africa. These maps will provide flood early warnings, enable climate-smart agriculture, and improve reservoir operations. Present near-real-time rainfall maps over Africa are 100% based on satellite data and are inaccurate to the extent that they have little to no operational value. More accurate maps combine satellite and ground data. Unfortunately, these have a long latency of one month or more, making them not usable for most operational applications.
The best approach to obtain accuracy in terms of timing, spatial distribution, and amount of rainfall is through an optimal combination of satellite data, ground data, and computer models. In general, ground data are sparse in Africa but, over the past decade, TAHMO has built and has been operating a network of 600+ weather stations in 23 African countries. Using data from these stations, which are available every hour in near-real time, is key to this initiative. Satellite data are still very much needed to interpolate between stations. There are exciting developments, such as Meteosat Third Generation (MTG) which provides meteorologically relevant images of Africa at 500m resolution six times per hour, and the radar-based constellation that tomorrow.io is launching, which provides global coverage once per hour, which will feed this development. Finally, computer models are necessary to tie it all together. Presently, algorithms typically have only one parameterization but with the advent of specialized machine learning, it will be possible to be location and season specific.
Quantified objectives. In terms of timeliness, we distinguish early products and daily products. Early products will have a latency of one hour and can support implementation of flood early warning systems, especially for urban areas and land-slides. The outputs will be categorical (no rain, normal rain, heavy rain, very heavy rain), according to local climates with a SEEPS score of 80% or better. Daily products will have a higher accuracy (SEEPS>90%, bias < 1 mm/day) and serve larger scale applications, such as hydrological modeling for reservoir management and index-based agricultural drought insurance. Especially insurance demands a high accuracy in terms of rainfall location as farms in Africa tend to be very small. MTG, which is about to become operational, will provide data at 500 m resolution, every ten minutes. A storm tracking approach that has been proven to work in Thailand will be combined with MTG data to have a categorical spatial accuracy of 500m.
Timely and accurate rainfall maps are a necessary condition for improvements of climate-smart agriculture, flood early warning systems, and reservoir operations. Presently, there are satellite-based rainfall maps available but their accuracy over Africa is low with over-estimation of the number of rainfall events, while underestimating the amount of rainfall per event. We are often talking about a difference of a factor two between satellite estimates and ground observations. Over longer periods and larger areas, the results tend to improve although we also see drift in the results once the number of ground stations used is reduced. Several satellite products are bias-corrected with ground stations but the latency of these products often are one month or more, due to the fact that the station data are not available in near-real time.
Presently, TAHMO operates a network of 600+ stations in 23 African countries. In our pilot countries (Kenya, Ghana, Uganda) the network has reached operational densities. Because TAHMO data on rainfall (and other weather variables) are collected at five minute intervals and are communicated every hour, there is a clear opportunity to use TAHMO data to: 1) Improve satellite rainfall products by adjusting algorithms and parameters, and 2) Provide near-real-time bias corrections.
Different applications have different demands in terms of accuracy and timeliness. For flood early warning systems, it may suffice to have categorically correct rainfall estimates (no rain,, normal rain, (very) heavy rain) as long as these estimates are timely. For climate-smart agriculture, accuracy in location is very important. For reservoir management, and large scale hydrological models in general, spatio-temporal distribution and absolute rainfall amounts are crucial. With the proposed approach, all demands can be met for all applications.
Based on estimates by the United Nations of the value of flood early warning systems alone, the proposed measures will have a benefit/cost ratio of more than ten.
