Hey there !
During day time earth absorbs the heat radiations of sun light.
At night earth is warmer than its surroundings so earth radiates energy absorbed to the surroundings and gets cooled slowly.
So that's why terrestrial radiation also happen at night.
Hope this helps !!

The Earth’s mean temperature is about 290 Kelvins (about 16 degrees C ) but varies a lot depending on location, time of year, and time of day. Earth radiates to the rest of the universe which is about 3 kelvins and does this constantly.
During the day it receives radiative energy from the sun, reflects some, absorbs some, and radiates the rest. At this time of year where I live in Southern California, USA, there’s about a 10 Kelvin difference between the high (daytime) temperature and the low (nighttime temperature).
The radiative loss of the earth is higher when it’s warmer which is during the afternoon not during the night.
