[Mastwatch] 2014 Mast event study

The problem with this is that, whereas rainfall from a nearby guage on the ground is likely to be fairly reliable, a ground-based tempeature reading, let alone one from outside the forest, is unlikely to accurately let alone consistently reflect canopy temperature - where mass flowering is overwhelmingly concentrated. Replicated canopy temperatures are a vital future research priority.

Hi Colin,

I do have daily rainfall for nearby Sukadana, and Andy Marshall and/or
Cheryl Knott may have rainfall and temp for within the park.

We had a long drought Jan-Feb, during which it always feels chilly at
night, but I don’t remember feeling/hearing about lower than usual temps.

What a great idea.  Let’s ask, “Who on this list might be able to provide:

 1) Their own temp/rainfall records for Jan-Jun 2014, or a commitment to
    seek out those data from nearby weather stations,
 2) Qualitative (descriptive) assessments of flowering/fruiting/recruitment,
 3) Quantitative (phenology, seedling plots) assessments of

Even a fairly rough study (4-5 sites & descriptive mast data only) would
be fun to try.
