NCEP/NCAR Reanalysis > Summary Table of Availability/File_Type

All file_types but the 8-day 12-hour forecasts are in our ds090.0 dataset. The 8-day 12-hour forecasts including pgb.fhhh and flux.fhhh file_types are in our ds090.1 dataset.

All products in ds090.0 are saved every 6 hours (4X per day). All file_types are synoptic sort unless otherwise noted.

• latlon,2.5 has 144x73 grids.
• Gaussian has 192x94 grids.
• 17 pressure levels: 1000, 925, 850, 700, 600, 500, 400, 300, 250, 200, 150, 100, 70, 50, 30, 20, 10 mb.
  
• 11 theta levels: 270, 280, 290, 300, 315, 330, 350, 400, 450, 550, 650 K.
  
• 28 sigma levels: [.9950, .9821, .9644, .9425, .9159, .8838, .8458, .8014, .7508, .6943, .6329, .5681, .5017, .4357, .3720, .3125, .2582, .2101, .1682, .1326, .1028, .0782, .0580, .0418, .0288, .0183, .0101, .0027]
  
• @V/L=variable/level combinations, or V=variables
  
• CRAY/IEEE format means the data is in cos-blocked cray binary format before May 1, 2000 and IEEE format after May 1, 2000.
