okay, so I've looked a little deeper and here's how it breaks down: 65% raw gridded data - 700GB/1.07TB 33% indexes - 350GB/1.07TBthe remaining 2% comprises header tables, coefficient tables, and sequencesso the large majority makes up just raw gridded dataand. "also . is any of the grid info transmitted in JSON? Or is it all just read infrom postgres?"yes, the data is pulled from the database and serialized to a JSON formattedstringwe use the simplejson library to do that, and 'dumps' methodi.e., simplejson.dumps(data)the serialized JSON string looks like:{'header': {'lo1': 0, 'la1': 90, 'dx': 2.5, 'dy': 2.5, 'nx': 144, 'ny': 73}, 'data':[long list of all data values to be plotted]}in other words, it's just a JavaScript object of key, value pairskeys are 'header' and 'data', and values are either another object of key, valuepairs, or a list containing the actual datathe data structure is analogous to nested dictionaries in Pythonthat's how JS handles dataand that's how Cambecc formats his data -- he runs the grib files through thegrib2json converter and produces exactly what I showed above
