In meteorology, the fog that is detected by satellite, radar and lidar?

Please give me The more detailed explanation, But please keep it simple!

Fog is a cloud on the surface. When I make a prediction that I use for a forecast Visible Satellite fog. Although there is a problem with this method, if the sun rises and visible satellite is practically zero. To avoid this problem, you must pass a two other methods. If you have access to a computer model that helps a lot. I tend to see a relative humidity at the surface and near the surface, 10 meter wind, and other products vorticity mixing (for example). Otherwise, you must use surface observations. When it comes to other methods they asked, could use a search radar and lidar fog. Radar and Lidar is sending signals and these signals bounce back against moisture and the radar data which are then is transformed into images. The disadvantage of these methods is that the radar is particularly useful to look over the surface. So you may or may not return fog. So when the temperature approaches the dew point (or when the relative humidity increases the value), which normally occurs during the night and morning (which is when forms of fog), the radar picks up additional moisture and this returns false positives (or floor space). But if I had to choose one of three things listed for forecasting fog that I would use satellite in the other two.
