Sunshine duration climate maps of Belgium and Luxembourg based on Meteosat and in-situ observations [PDF]

open access: yesAdvances in Science and Research, 2013
Sunshine duration was historically the traditional parameter to quantify solar radiation. In the present study, we propose to benefit from the measurements made with Campbell-Stokes recorders at 18 sites in Belgium and Luxembourg to generate maps of ...

Estimation of Daily Sunshine Duration from Terra and Aqua MODIS Data [PDF]

open access: yesAdvances in Meteorology, 2014
Some studies have shown that the estimation of global sunshine duration can be done with the help of geostationary satellites because they can record several images of the same location in a day.

Exploring lag and duration effect of sunshine in triggering suicide

open access: yesJournal of Affective Disorders, 2005
Sunshine is considered to have a beneficial impact on mood. Interestingly, it has been consistently found that the incidence of suicide reaches a peak during early summer.In order to explore the pattern of sunshine and suicide risk in a time frame of up to nine days and investigate possible lag and duration parameters of sunshine in the triggering of ...
