Transport Indices computed from monthly mean fields from
FNMOC six-hourly Atmospheric Pressure at Mean Sea Level analysis fields (73x144)
Columns Description Dates: 1981013118 through 2000123118

1 - 4 Year
5 - 6 Month (mm=01 => January)
7 - 8 Day of Month (dd=01 => 1st)
9 - 10 Hour of Day (hh=00 => midnight Universal Time)
or Number of Fields in daily or longer Mean product
or Hour+Number for 12hourly Means (00+2=2,12+2=14)
11 - 15 Latitude (hundredths of degrees, North > 0, South <0
16 - 21 Longitude (hundredths of degrees, East > 0, West < 0
22 - 26 Mean Sea Level Atmospheric Pressure (value +10,000)/10 => mb)
27 - 31 Northward Component of MSL Wind (decimeters/sec)
32 - 36 Eastward Component of MSL Wind (decimeters/sec)
37 - 41 Northward Stress (value x 1.0E-3 => Stress Index in dynes/cm**2)
42 - 46 Eastward Stress (value x 1.0E-3 => Stress Index in dynes/cm**2)
47 - 51 Wind Stress CURL (value x 1.0E-10 => Curl Index in dynes/cm**2/cm)
52 - 56 Wind Speed Cubed ((m/sec)**3)
57 - 61 Northward Ekman Transport (value x 10 => Transport in metric-tons/sec/km)
62 - 66 Eastward Ekman Transport (value x 10 => Transport in metric-tons/sec/km)
67 - 71 Offshore Ekman Tr. (Upwelling Index in metric-tons/sec/100-meters-of-coast)
72 - 76 Offshore Direction along which Upwelling Index is resolved (degrees true)
77 - 81 Upward Vertical Velocity into Ekman Layer (mm/day excluding Coastal Diverg.)
82 - 86 Sverdrup Wind Stress CURL Tr. (value x 100 => Northward metric-tons/sec/km)
******The value 0.0026 was used as Drag Coefficient in the stress computations.******
The indices are in GMT or Zulu(Z) time.
Units of the Ekman transports are cubic meters/second/100 meters of coastline
