The main conditions to look for are increased atmospheric transparency, opacity and the time of day. The early morning and late evening can create a stark shadow cast but don't go too deep on the shadows or they can overlap and block other views. Early mornings may retain fog until the afternoon sun burns it off.
Seasonal variations may cause fog in the morning and rain mist and haze will all block viewing. Do not exceed the criteria of magnification per unit inch aperture and do employ methods of amping the equipment. Stop study and protects all instruments and accessories during periods of air pollution and smoke as it can etch and ruin a delicate telescopes surface optics dielectric glass and mirror coatings. Light mist can deliver high concentrations of acid rain, which is deadly to humans and scientific equipment.
The correct character selection filters will penetrate the atmosphere resulting in greater clarity. Red and IR are both atmosphere penetrating so choose a CCD with matching sensitivity. Use a manually positioned mount and a camera holder for stability. Once a subject of protracted study is found, capture video for later processing. Capture stills of high resolution for counting plants and mapping the distribution of forest jungle. Remember, the elevation of the mountain will determine the range possible for the study. A flat plane shows detail out to about 24 miles, after which the curvature of the Earth will block the surface features.
