Solar Insolation in Oslo, Norway in June

What is the average solar insolation Location A (Oslo, Norway) received in June?

a. Near 0 W/m²
b. Near 275 W/m²
c. Near 400 W/m²
d. Near 550 W/m²

Answer:

The average solar insolation at Location A (Oslo, Norway) in June, considering the latitude and solar declination of this place, would be approximately 400 W/m², assuming typical atmospheric conditions and ignoring obstructions like clouds and buildings.

Solar insolation is a crucial factor in determining the amount of solar radiation energy a particular location receives. In the case of Oslo, Norway, located at around 60° N latitude, the average solar insolation in June is significantly influenced by the Earth's tilt and the duration of daylight in the region during this time of the year.

During the June solstice, regions close to the North Pole, including Oslo, experience extended daylight hours, with some areas receiving 24-hour daylight. This prolonged exposure to sunlight contributes to higher solar insolation levels in June compared to other months of the year.

However, despite the increased daylight, Oslo's northerly location results in the sunlight striking the ground at a lower angle, leading to a spread of radiation over a larger area. This angle of incidence affects the intensity of solar insolation, with locations closer to the equator receiving more direct sunlight and higher insolation levels, even during summer months.

Considering factors such as Oslo's latitude, solar declination, and seasonal variations in solar radiation, an estimate of 400 W/m² for the average solar insolation in June aligns with the regional conditions and atmospheric influences in Oslo, Norway.

For a deeper understanding of solar insolation and its impact on different locations, it is essential to explore the effects of latitude, solar declination, and seasonal variations on solar radiation distribution. By considering these factors, we can better estimate and interpret the average solar insolation levels in regions like Oslo, Norway, during specific times of the year.
