August 2000

• Change wxcommon.js to workaround Communicator 4.74 change.

August 1998

• Experimenting with HTML 4.0 code that enables better keyboard navigation for those browsers that support it.
• Corrected links to sites that have moved.
• Added weather, astronomy, and calculator links.

June 1998

• Corrected wind chill in celsius calculation.
• Corrected location of parenthesis for e in CalcWithWb.

March 1998

• Corrected use of relative humidity in calculating heat index.

December 1997

• Updated Atmosphere Calculator and Humidity Calculator to calculate saturation vapor pressure when just temperature is given.

November 1997

• A link was added to the sunrise/sunset calculator page.
• The wind speed conversion to and from miles per hour and knots was backwards.

October 1997

• Specific humidity is now computed for g/kg instead of g/g. Documentation for absolute humidity and specific humidity updated.

For the week ending August 30, 1997

• Added Weather Algorithms For Computer Programs page.

For the week ending August 23, 1997

• Made certain output text boxes read-only.

For the week ending August 16, 1997

• Added the wind chill unit Canadians really use to the wind chill calculator.
• Added a humidity calculator that is similiar to Atmosphere Calculator but more focused.
• Added a unit conversions page for converting temperature, pressure, and wind units.
• Added the wind chill unit Canadians use to the wind chill calculator.

For the week ending August 9, 1997

• Added a version of Atmosphere Calculator for Netscape 3 or later. This version has substantially rewritten code that has been put in to seperate modules. Uses a common set of code shared with the two calculators below and can be used with any other calculators I come up with. Trimmed the amount of space given to values to allow for two columns of variables.
• Added a wind chill calculator.
• Added a heat index calculator.
• New behavior starting with this batch of updates and additions: Input variables are no longer rounded on screen (they were never rounded for computations). Output variables are now rounded based on the unit e.g. inches are rounded to two places, millibars none.
