I posted this question on Aviation Stack Exchange here. One of the responses suggested that I post my question on Earth Science Stack Exchange.
I need a source that reports necessary current cloud data to determine cloud height or cloud type (Cirrus, Stratus, Cumulus, etc.). I do not need historical data and, for now, I do not need forecast data. Current data only.
I found a question/answer for determining the bottom of the cloud but I can't find it again. I found some relative information in Aviation Stack Exchange and one answer here that tells how to find the cloud tops but I'm posting this question anyway in case there is resource yet to be suggested. I'm giving up on the idea of an API but still hopeful that there are some resources and techniques we can use to acquire this information.
BTW: I am not a weather specialist. I am a Software Engineer and we need this information for Ballistic Missile accuracy. We need to know the weather conditions but cloud data is the most important and yet missing piece.
