>> * Last Update: January 23, 2001<br>
>> *<br>
>> * Recent Changes:<br>
>> *<br>
>> * 01/23/01 - Fixed a small bug in the theta-e calculation.<br>
>> * Errors averaged 0.5-3K. Thank you George Bryan.<br>
>> *<br>
>> * 11/10/99 - Change in calculation method for CAPE/CIN. Trapezoid<br>
>> * integration method is now used. Speeds up execution<br>
>> * by 25%, and increases accuracy by 5-10%.<br>
>> *<br>
>> * 10/18/99 - Minor glitch fixed that occasionally caused crash.<br>
>> *<br>
>> * 8/26/99 - Datasets with missing data can now be used.<br>
>> *<br>
>> * Features:<br>
>> * - All features of standard skewt/logp plot<br>
>> * - RH sounding<br>
>> * - LCL location<br>
>> * - Parcel trajectory for both sfc based convection and elevated from<br>
>> * most unstable level (highest theta-e level reported)<br>
>> * - Stability indices and precipitable water calculations<br>
>> * - CAPE & CIN Calculations<br>
>> * - Wind Profile<br>
>> * - Hodograph / Hodograph scaling<br>
>> * - Helicity and SR Helicity Calculations and Display<br>
>> * - Color aspects of output<br>
>> * - Line Thickness, style aspects of output<br>
>> * - Can be run in either PORTRAIT or LANDSCAPE mode.<br>
>> *<br>
>> * There are numerous tunable parameters below to change the structure<br>
>> * and output for the diagram.<br>
>> *<br>
>> * Function Arguments:<br>
>> * sndtemp - temperature data (Celsius) as a function of pressure<br>
>> * snddewp - dewpoint data (Celsius) as a function of pressure<br>
>> * sndspd - wind speed data (knots) as a function of pressure<br>
>> * snddir - wind direction data as a function of pressure<br>
>> *<br>
>> * Use '-1' for any of the above 4 arguments to indicate that you<br>
>> * are not passing that variable. The appropriate options will<br>
>> * be ignored based on your specifying '-1' for that variable.<br>
>> *<br>
>> * NOTE: Make sure to set the vertical range of the plot before running.<br>
>> * I.e., "SET LEV 1050 150", for example. This does not have to<br>
>> * be limited to the pressure range of your data.<br>
>> *<br>
>> * Labelling: Pressure/Height is labelled along left side. Temperature is<br>
>> * labelled along bottom. Mixing ratio is labelled along right<br>
>> * side/top.<br>
>> *<br>
