Solar Radiation Resource

2018
The sun is the main source of renewable energy. It emits radiation at an equivalent black body temperature of about 6,000 K with a constant intensity outside the earth’s atmosphere. Only direct (beam) radiation is available outside the earth’s atmosphere.

Σε αυτή τη διδακτορική έρευνα, μελετάται η επίδραση της απορρόφησης της ακτινοβολίας από τα αερολύματα στο ενεργειακό ισοζύγιο καθώς και στις ατμοσφαιρικές παραμέτρους στη λεκάνη της Μεσογείου σε αντιπροσωπευτικές θερινές περιόδους. Η απορρόφηση του κάθε αερολύματος εξετάζεται μεμονωμένα: μαύρος άνθρακας, σκόνη, αλάτι, καφέ άνθρακας.
