Challenge Problems
Push your limits with advanced challenges
A lake has an Rn value of 10 MJ/m2/day during a summer day, while a snow-covered field has an Rn of 3 MJ/m2/day. Discuss the factors leading to this difference.
💡 Hint: Think about the properties of water versus snow.
Calculate the Net Radiation if Rs is 20 MJ/m2/day and α is 0.2, with Rnl at 4 MJ/m2/day.
💡 Hint: Apply the formula step-by-step.
