SATELLITE BASED DOWNSCALING ALGORITHM FOR RAINFALL ESTIMATION

Although rainfall estimates are a key environmental parameter, they are not always available at an appropriate scale and with a sufficient accuracy. Satellite based rainfall estimation methods supply valuable information and their enhancement is a key issue. In this paper we describe a rainfall estimation method based on MSG, the new European meteorological geostationary satellite. Computations have been carried out on West-Africa during 2004 rainy seasons. Our algorithm is composed of two parts: assessment of rainfall probability and actual rainfall estimation. Rainfall probability is computed by comparing MSG derived indicators with TRMM/PR rain detection. After the selection of input nodes, a feed forward neural network is trained. The network coefficients being assessed, rainfall durations can be computed. The second part of the algorithm merge rain probability data with actual rainfall measurement. This part is highly dependent of available rainfall data. If precipitations are supplied as gridded data, a potential intensity is first computed and then precipitations are downscaled at intitial satellite resolution. On 2000 data, resulting rainfall estimates have been tested against GPCP on a dense raingauges network and have demonstrated better performances

Cattle methane fluxes measurement over an intensively grazed grassland using eddy covariance

audience: researcherMethane emissions account for 8% of the EU-15 GHG emissions and livestock generates approximately half of these emissions (European Commission, 2009). Recent technological advances in spectroscopy now permit methane flux measurement using eddy covariance. This method has numerous strengths. It can measure fluxes in situ, continuously and across broad areas. This provides information about meadow and cattle emission behaviour throughout the year and across a broad range of climatic conditions. We will present here a one year monitoring of methane exchange between an intensively grazed meadow and the atmosphere obtained using the eddy-covariance method. Methane fluxes exchanged by a grazed meadow were measured continuously since June 2012 at the Dorinne Terrestrial Observatory (50˚ 18’ 44” N; 4˚ 58’ 07” E; 248 m asl.) in Belgium. The site is an intensively pastured meadow of 4.2 ha managed according to the regional common practices where up to 30 Belgian Blue cows are grazing simultaneously. Flux measurements were made with the eddy covariance technique, using a fast CH4 analyzer (Picarro G2311-f) and a sonic anemometer (Campbell Csat3). Carbon dioxide fluxes and various micro-meteorological and soil variables, biomass growth and stocking rate evolution were also measured at the site. Turbulent fluxes were calculated according to standard eddy covariance computation schemes and were filtered for non-stationarity and for low friction velocity (u*) events. During grazing periods, fluxes are dominated by the enteric fermentation source and average 111 nmol m-2 s-1. They are highly variable, probably due to cow movements in and out the measurement footprint and cow digestion rhythm. Despite this spread, a daily emission rhythm is observed with higher emissions during the afternoon. When fluxes are integrated over large periods, methane emissions were found strongly related to cattle stocking rate with a slope of 7.34±0.78 mol CH4 day-1 LSU-1. Further developments are ongoing in order to improve cattle geo-localization through infra-red cameras and individual home-made GPS devices. The two systems will be compared in terms of cost, efficiency and ease of use. During cow-free periods, the methane flux averages 10.5 nmol m-2 s-1 and is highly variable with some production peaks above 100 nmol m-2 s-1. No relation was found between methane fluxes and soil temperature while a weak negative relation was found between methane fluxes and soil humidity. No soil methane absorption has been observed.
