The DYVALOCCA project is a collaboration between French, German and Gabonese partners. Reuniwatt’s Sky InSight™ (infrared all-sky imager) was used during a field campaign to monitor the evolution of clouds<\/span> and evaluate their effects on water and light<\/span> availability in a forest al<\/span><\/span><\/span>ong the Atlantic coast of Central Africa.

Low clouds are key components of climate. However, they are rarely well represented in weather and climate models. Along the Atlantic coast of Central Africa, from the coastal plains of Gabon and Congo-Brazzaville to the interior plateaus, a unique cloudy dry season develops from May to September. The region’s dense evergreen forests might be particularily vulnerable to climate change as any reduction of these low clouds may represent a major tipping-point for forest cover and functioning.<\/p>\n

The DYVALOCCA project was funded by the French and German research agencies (ANR and DFG) to collect existing in-situ data and satellite estimates to establish diagnostic and modelling analyses of the dynamics and variability of these low clouds. With a range of measurement material (<\/span><\/span>Ceilometer<\/span><\/span>, <\/span>Disdrometer<\/span><\/span>, <\/span>Sodar<\/span><\/span>, <\/span>Microwave sounder<\/span><\/span>, <\/span>Tethersondes<\/span><\/span> and radiosondes<\/span><\/span>,<\/span> infrared sky imager), the research consortium, co-led by Dr. Nathalie Philippon (CNRS researcher at IGE), has been developing the first conceptual model for low-cloud formation and dissolution in western equatorial Africa, in order to provide a basis for development of intraseasonal to seasonal forecasts of low cloud variations, and quantify the water and light constraints underneath the low clouds. The project’s results will also give directions for an evaluation of climate change simulations with a focus to inform the assessment of tipping-points for the evergreen forests in past and future climates.<\/p>\n

When it comes to monitoring different parameters related to climate change, photonics hold an important role, with space-based applications and in-situ measurement devices. Learn more about how Reuniwatt’s skycam Sky InSight™ helps monitor the low cloud cover in Gabon, and the broad range of applications of photonics for climate research during t<\/span>he full replay of the EPIC Online Technology Meeting on Photonics for Climate Change from April 24, 2023.<\/div>\n
