What is the typical size of the sulfuric acid droplets in the atmosphere of Venus?

According to Wikipedia:

Venusian clouds are thick and are composed mainly (75-96%) of sulfuric acid droplets. These clouds obscure the surface of Venus from optical imaging, and reflect about 75% of the sunlight that falls on them. The geometric albedo, a common measure of reflectivity, is the highest of any planet in the Solar System. This high reflectivity potentially enables any probe exploring the cloud tops sufficient solar energy such that solar cells can be fitted anywhere on the craft. The density of the clouds is highly variable with the densest layer at about 48.5 km, reaching 0.1 g/m^3 similar to the lower range of cumulonimbus storm clouds on Earth.

Can the typical size of the sulfuric acid droplets in the atmosphere of Venus be estimated from observation, or from calculation based on models of the atmosphere? Would the average size be expected to vary with altitude?

• Possibly helpful: 1, 2, 3 It looks like the droplets are thought to be roughy in the 0.1 to 1μm range.

• @uhoh Thank you very much for your valuable information and for the editing of my question ! It looks much more scientific now. Jan 28, 2018 at 16:05
• It's an interesting question! In Stack Exchange it's always better to do at least some research first, and to post what you know already. That helps guide others to understand better what will be needed for an answer. I'm sure you've done some reading already since you know there are sulphuric acid droplets, but its always better to mention in the question how you know.

• @uhoh I asked this question because i wanted to know if oxygen producing bacteria would fit in the droplets. Now i know for sure, not in the upper cloud region.! Jan 28, 2018 at 16:23

TL;DR: Since no one is answering, I am taking take the responsibility. Yes, just like @uhoh said, there are two size modes with mean radii ~0.2 µm (mode 1) and ~1 µm 60 (mode 2), along with a third, controversial mode with radius ~3.5 µm.
