Surface Conditions and Measurements

Surface Conditions (Mandatory)

Surface Conditions are an important part of the Cloud Protocol observations. When we look up, we are differentiating between a blue sky and mostly white clouds. When a satellite is trying to categorize clouds versus other geographical elements there are many more colors involved and it can sometimes be difficult to tell the difference between ice and snow or clouds. By reporting surface conditions, you are providing additional data to assist during analysis and satellite validation.


  • A pond would be an example of standing water.
  • Leaves on trees refers to the majority of the deciduous trees around your observation site.

Surface Measurements (Optional)

Air Temperature, Barometric Pressure and Relative Humidity are optional. Unless you have been trained in the associated GLOBE Protocol, skip surface measurements.

E-Training slides for the above Surface measurements can be found under the Atmosphere E-Training suite.
