RJN wrote:It seems to me that snow has the possibility of accumulating even more micrometeors on the way down than rain. The reason is that snow typically has a slower terminal velocity than rain. Now micrometeors surely hit a terminal velocity on the way down themselves. I would guess, though, that the smaller and more dense micrometeors have a higher terminal velocity than both rain and snow. So, to exaggerate for clarity, a snow flake is essentially "frozen" (hah!) in the air as micrometeors hit them from above. A snowflake therefore both stays in the air longer than a raindrop, and has a more different terminal velocity than a raindrop. To reiterate, both effects may make snow a better micrometeorite catcher than rain. But the cool thing about science is that we will see! Any other bets?
5.0 m/s 1mm raindrop terminal velocity
1.0 m/s Average snowflake terminal velocity
0.5 m/s 50 micrometer meteorite terminal velocity
0.1 m/s 20 micrometer meteorite terminal velocity

2. First does the snowflake collect particles as it falls down? The rain drop does, and my intuition says the snowflake does but, I have no hard data. If the snowflake doesn’t then the rain would be more efficient at collecting particles.

Am also considering, the heaviest particles are released from the cloud at the middle of the rainshower.
What code did you use?
Been away a few days...but judging by the new "Code" button
I guess that you figured this out for yourself.
"Code" is useful for tables and the like.

What about all the others that are nonmagnetic?
