We present a new model for the calculation of the diffuse fraction of the global solar
irradiance for solar system simulations. The importance of an accurate estimation of the …

Four methods have been used for the estimation of the total cloud amount and cloud amount
for low clouds: visual observations, the Long method applied on pyranometer …

The climate in the Arctic has warmed much more quickly in the last 2 to 3 decades than at
the mid-latitudes, ie, during the Arctic amplification (AA) period. Radiative forcing in the …

Characterizing the atmosphere is one of the most complex studies one can undertake due to
the non-linearity and phenomenological variability. Clouds are also among the most …

The accurate identification of the presence of cloud in the ground scenes observed by
remote-sensing satellites is an end in itself. The lack of knowledge of cloud at high latitudes …

The thermal infrared cloud camera (IRCCAM) is a prototype instrument that determines
cloud fraction continuously during daytime and night-time using measurements of the …

The current study analyses the cloud radiative effect during the daytime depending on cloud
fraction and cloud type at two stations in Switzerland over a time period of 3 to 5 years …

Predicting cloud cover is essential in fields, such as agriculture, climatology, and
meteorology, where accurate weather forecasting can significantly impact decision-making …

This paper presents a method to calculate surface UV index maps from SEVIRI satellite
images using a very simplified approach to account for clouds. We compare the resulting …
