Part 107 UAS pilot reported they were flying during times of intermittent VFR weather conditions. The UAS crew chose to land and wait for better weather.

Narrative

I was operating a UAS for the purpose of news gathering in a weather damaged area. Upon arrival at the location at approximately XA:00; my observation was that the weather was below minimums estimated at less than 1/2 SM visibility in mist with the sky obscured. No nearby METARS were available. I waited approximately 1 1/2 hours when daylight arrived and clearing began to occur. Based on my ground observation and visibility of a nearby tower; and with clear skies directly above I elected to launch the UAS. Law enforcement and at least one other news gathering UAS did the same. At an altitude of ~75 ft. AGL; when panning in all directions and using the live feed from the UAS camera as a guide; I believed that I had met the minimum requirements of cloud clearance and visibility. However the conditions quickly lowered again and I landed the UAS. The other UAS I observed also landed after I did. Later; the weather improved remarkably and further flights were not questionable. With a very limited view of the horizon due to local obstructions; lack of a nearby METAR and PIREPS we are often faced with situations where best judgement on weather estimation is all we can do. In my case; with the weather conditions at the time; I remained within 200 ft. of the launch point and went no higher than 75 ft. AGL. The live camera feed was helpful in determining visibility as I could clearly see the rotating beacon at ZZZ as well as distinguish obstacles in the distance. A ceiling requirement at my altitude of 75 ft. AGL would have been 600 ft. and it was very difficult if not impossible to judge that. From a safety standpoint however; there would not have been any chance of interfering with another aircraft and the visual observer I had with me always had visual contact with the other two UAS.
