Hi Pawan,

I once wrote lonlat2reg() which can be found here:
http://wew.met.fu-berlin.de/idl/lonlat2reg.pro

Input can be any arrays or vectors with (irregular) longitude /
latitude and data information. Output is a structure with the number of
irregular data points in each regular grid box, their sum, squared sum
and average, standard deviation and the lon / lat values of the grid
center. The target regular grid is defined via keywords. You choose the
lower left corner, the size of each grid and the number of grid boxes.
N.b. the lower left corner is the lower left corner, not the center of
the lower leftmost grid box.

And yes, it uses histogram and reverse indices!

Cheers,

Peter
