Today is a sunny day. I came in front of a Thermometer screen
box, ready for weather observation. The Thermometer screen is about a global
program for science and education, whose purpose is to provide a standardized
environment in which we can measure temperature, surface temperature, humidity,
precipitation and atmospheric pressure. I learned much relevant knowledge from
observing, which enables me to pay more attention to the environment.
The whole screen is painted with several coats
of white to reflect sunlight radiation.
Today's cloud genus is Altocumulus. It is a
middle-altitude cloud genus. It looks like lots of marshmallows.
