This paper reports on a new satellite sensor, the Geostationary Earth Radiation Budget (GERB) experiment. GERB is designed to make first measurements of Earth's radiation budget from geostationary orbit. Measurements at high absolute accuracy reflected sunlight Earth, and thermal emitted by are made every 15 min, with spatial resolution subsatellite point 44.6 km (north–south) 39.3 (east–west). With knowledge incoming solar constant, this gives primary forcing response components...
Seventy-one sensitivity experiments have been performed using a two-dimensional sectoraveragedglobal climate model to assess the potential impact of six different factors on lastmillennium and in particular surface air temperature evolution. Both natural(i.e, solar volcanism) anthropogenically-induced (i.e. deforestation, additional greenhousegases, tropospheric aerosol burden) forcings considered.Comparisons reconstructions with results indicate that all investigated are needed simulate Due...
Abstract Predicting how the timing of cyclic life‐history events, such as leafing and flowering, respond to climate change is paramount importance due cascading impacts vegetation phenology on species ecosystem fitness. However, progress this field hampered by relative scarcity, geographic phylogenetic bias, long‐term datasets. By taking advantage archived television video footage, we here developed an innovative tool using previously unexploited records build datasets phenological...
Increasingly, mesoscale meteorological and climate models are used to predict urban weather climate. Yet, large uncertainties remain regarding values of some surface properties. In particular, information concerning for thermal roughness length admittance is scarce. this paper, we present a method estimate in combination with an optimal scheme length, based on METEOSAT‐8/SEVIRI infrared imagery conjunction deterministic atmospheric model containing simple urbanized land scheme. Given the...
Besides the low frequency variations, Earth's orbital elements also exhibit variabilities at shorter time scales. This study investigates quantitative impact of these high orbitally induced insolation variations on climatic variables such as surface temperature well dynamical change in vegetation. Moreover it aims to assess extent which different factors (high and subsequent vegetation changes) may compete with changes solar activity. To this end, we have carried out a series transient...
Abstract The method used to estimate the unfiltered shortwave broadband radiance from filtered radiances measured by Geostationary Earth Radiation Budget (GERB) instrument is presented.

This paper presents a new dataset of quality controlled and homogenized monthly mean air temperature for Belgium. After in‐depth data control, maximum minimum time series have been with the HOMER software on basis available metadata. Homogenization results are provided 61 over period 1954–2015 16 starting before 1931 including eight covering full 1880–2015. The allows to make robust analysis evolution in Belgium at local scale from 1880 nowadays. Trends temperatures indicate average similar...
Abstract. Investigations are conducted to best estimate precipitation climate maps over Belgium from daily observations available for the period 1981–2010. Several mapping approaches compared in a cross-validation exercise. These differ by several aspects and particular order which temporal aggregation (i.e. computation of mean values data) spatial interpolation steps performed, integration ancillary information method. The selected approach is used derive large panel maps. In particular,...
A new method to estimate composite top of the atmosphere (TOA) visible clear‐sky reflectances for wide narrow band geostationary satellites such as Meteosat constellation is presented. This relies on some a priori knowledge angular variations TOA broadband associated with conditions above mean surface types through use Cloud and Earth's Radiant Energy System (CERES) shortwave dependency models (ADMs). Each pixel (or Earth location) viewed from imager at given daytime reflectance time series...
Abstract. In the framework of interdisciplinary FORBIO Climate research project, Royal Meteorological Institute Belgium is in charge providing high resolution gridded past climate data (i.e. temperature and precipitation). This set will be linked to measurements on seedlings, saplings mature trees assess effects variation tree performance. paper explains how daily (minimum maximum) was generated from a consistent station network between 1980 2013. After selection, quality control procedures...
As more and meteorological stations are working in a fully automatic mode, the classic Campbell–Stokes instrument for measuring sunshine duration becomes obsolete. consequence, situ observations of daily over Belgium become sparse require extensive interpolation to produce spatially complete fields. Two different approaches combining ground station geostationary satellite data estimate at pixel level evaluated here. The analysis uses solar radiation parameters retrieved from Meteosat Second...
Solar radiation data are essential for many applications, and in particular solar energy systems. Because ground-based measurements of usually scarce, several methods have been proposed to estimate the incoming on a horizontal surface at ground level from satellite imagery. These satellite-based estimations can be used as such, or combined with measurements. sets differ spatial temporal resolution, this study evaluates sensitivity satellite-derived daily irradiation underlying space time...
