A. Data Set AB<br />

Twelve-hour pressure and temperature fields. These data can be read<br />

with the following FORTRAN statements:<br />

INTEGER LAT, LD, LH, LONG, LM, LY, PX, PXX, PXY, PY, PYY<br />

REAL EP, ET, P, T<br />

READ (,1) LY, LM, LD, LH, LAT, LONG, P, T, EP, ET, PX, PY, PXX,<br />

PXY, PYY<br />

1 FORMAT (4I3, I4, I5, F8.1, F7.1, 2F5.1, 2I5, 3I6)<br />

LY is the year less 1900.<br />

LM is the month; 1 for January, 2 for February, etc.<br />

LD is the day <strong>of</strong> the month.<br />

LH is the hour in GMT; LH = 0 or 12.<br />

LAT is the latitude in degrees north.<br />

LONG is the longitude in degrees east.<br />

P<br />

is the interpolated pressure in millibars.<br />

T<br />

is the interpolated temperature in degrees Celsius<br />

averaged from LH - 12 to LH + 12 hours.<br />

EP is the interpolation error variance in millibars squared.<br />

ET is the interpolation error variance in degrees Celsius<br />

squared.<br />

PX, PY are the pressure derivatives times 10 3 in the x and y<br />

directions. PX and PY have units <strong>of</strong> millibars per 10 3<br />

kilometers.<br />

PXX, PXY, are the interpolated second derivatives <strong>of</strong> pressure times<br />

PYY 10 6 . Their units are millibars per 10 6 kilometers.<br />

B. Data Set C<br />

Twelve-hour buoy positions. These data can be read with the following<br />

FORTRAN statements:<br />

INTEGER<br />

REAL<br />

ID, LD, LH, LM, LY<br />

LAT, LONG<br />

READ (,1) LY, LM, LD, LH, ID, LAT, LONG<br />

1 FORMAT (4I3, I6, F7.3, F9.3)<br />
