The temperatures may plummet to as low as minus 190 degrees Fahrenheit .Researchers at Germany's Berlin Technical University have now attempted to learn more about how much snow accumulates at Mars' north pole throughout the year.
For this study, the researchers assessed the total buildup of snow and ice at Mars' northern pole and then compared their estimations to previous measurements obtained by NASA's MOLA probe. They used measurements based on the shadows cast by ice blocks inside the North Polar Layered Deposits to calculate the depth of seasonal snow deposits. This was done with the help of shadows seen in NASA's HiRISE images.
“We propose to use the shadow variations to infer the seasonal depths at high polar latitudes,” the authors mentioned in theThe findings demonstrated that when temperatures varied across a Martian year , these deposits changed, including the shadows they cast. It was constantly noted that the quantity and depth of snowfall reduced from winter to spring.It may reach about a meter in thickness during peak winter, then drop to around 0.21 meters in spring.
