Fisheye pictures are frequently used in forestry and in ecology for canopy measurements. In climatology, it seems that they have only been used for illustration purposes. In fact, fisheye pictures are rich in climatological information. Digital fisheye image processing can be used for applied climatology as well as for topoclimatological studies. It allows the quantification of insolation, diffuse radiation, sky-view factor,.… In other words, it provides an objective assessment of the exposure of a site or of a measuring device. This article introduces the basis for digital fisheye image processing. The possibilities offered by this tool will be illustrated with sunshine measurements in an urban environment. [less ▲]

The fluctuations of annual precipitation observed in Niamey and Zinder (Niger) since the turn of the century warranted a comparison of rainfall maps and rainy-season characteristics between 1950-1967 (period of high rainfall) and 1968-1985 (period of low rainfall). Calculating two specific annual spatiotemporal rainfall profiles provided precisions as to the irregular and heterogeneous advance of the drought through Niger. [less ▲]

In Belgium, air masse advections -as it appears at 850 hPa level- are very important for the explanation of the surface air temperature of mild winters. Nevertheless in case of severe winters, radiative conditions observed at tropospheric lower level and horizontal motion of very thin air masses (below 850 hPa level) seem to be more important for the explanation of ground level temperature.
