Rain Drop Project

Objectives

1. characterize raindrop size distributions (kung gamma ba talaga siya)
2. weibull we can only do this if we're looking on actual data, right?
3. relate the two parameters of the gamma distribution to each other
4. Make a simulation using several factors, and relate those factors to the DSD parameters.

To Do

1. Verify if there is still doubt that DSD is really gamma. I think it is accepted that it is gamma.
1. If we accept it too, we must give some sort of empirical proof that is not shown before. Otherwise, if we accept it and not (be able to) give a proof, we have no choice but to make it an assumption.
2. If we do not accept it, we'll also need an empirical proof plus an alternative model.
2. Study instrumentation: how it is measured and sampled?
3. Gather sources of raindrop measurement datasets.

Simulation Model

1. Physical processes included
1. coalescence - fusion of drops
2. breakup - opposite of coalescence
3. accretion - growth of a cloud or precipitation particle by the collision and union of a frozen particle with a super-cooled water drop (using google's define: accretion)
4. evaporation -
5. updraft - a small-scale current of rising air (using google's define: updraft)
6. downdraft
2. Other parameters
1. rain intensity
2. evaporation probability

Datasets

• ISCCP (International Satellite Cloud Climatology Project)
• NASA TRMM (Tropical Rainfall Measurement Mission)
