Drawing+Conclusions+from+METAR+Data

=Step 1: Data Conversion Sheet= We need to change our data to make it easier to use. Use the following to fill in the **data conversion worksheet**
 * 1) Airport Code write the airport codes from your METARs
 * 2) Day (Do not write anything in) Day 1 is your first sheet, Day 2 is the second, etc.
 * 3) Temperature copy from the temp box on your METAR journal
 * 4) Dewpoint copy from the dew point box on your METAR journal
 * 5) If your pressure reading starts with an A (A2920, A3010) then fill in the Pressure (inches of HG) if your pressure reading starts with a Q (Q1000,Q0988) then fill in Pressure (mb).
 * 6) Use the Pressure chart from the reference tables to convert to the empty box
 * 7) Wet Bulb & Relative Humidity come from a Humidity Online Calculator
 * 8) Click the link
 * 9) Make sure the advanced tab is selected
 * 10) Type in Temperature and Pressure (mb) from your sheet in the top, type in Dew Point in the bottom section, don't change the other values.
 * 11) Click calculate button at bottom
 * 12) Copy Wet Bulb and Relative Humidity onto your sheet.

=Step 2: Graphing Weather Data= Now that we have our data is a useful form, we can do some comparisons
 * 1) Open Create-A-Graph
 * 2) Click on XY
 * 3) Select Scatter, and you can pick your colors
 * 4) Click the data tab on the right side
 * 5) Fill in the following on the data tab
 * 6) Name of the graph: Temperature vs. Dewpoint
 * 7) X Axis Label: Temperature (C)
 * 8) Y Axis Label: Dewpoint (C)
 * 9) Data Set 5 Points and 5 Groups
 * 10) Group Label is the Airport Code
 * 11) Point Shape, Size and Color are up to you
 * 12) Put the temp in the top box (x) and the dew point in the (y) box for all 25 points
 * 13) Min Value X=-15 Y=-15
 * 14) Max Value X=30 Y=30
 * 15) Click to the label tab, you can change whatever you want to here
 * 16) Preview the Graph to make sure it looks right
 * 17) Click Print/Save Tab
 * 18) Click download change it to PNG and click download
 * 19) Click open on the box that pops up.
 * 20) Copy and paste the graph into a Word File. Put all your graphs in the same word file. Make sure you keep on saving your file


 * Now you need to repeat the process for the following**:
 * Air Temperature vs. Wet Bulb
 * Wet Bulb (C) on the Y
 * Update the title and labels
 * Update the data, you should only have to change the Y values from the last one
 * Air Temperature vs. Relative Humidity
 * Relative Humidity (%) on the Y
 * Update the title and labels
 * Change Y Min=0, Y Max=100
 * Update the data, you should only have to change Y values from the last one
 * Air Temperature vs. Pressure
 * Pressure (mb) on the Y
 * Update the title and labels
 * Change Y Min=950, Y Max=1050
 * Update the data, you should only have to change Y values from the last one
 * Relative Humidity vs. Pressure
 * Relative Humidity (%) on the X, Pressure (mb) on the Y
 * Update title and labels
 * Change X Min=0, X Max =100
 * Update the data, you should only have to change X values from the last one
 * Relative Humidity vs. Difference between Air Temp and Wet Bulb
 * Difference between Air Temp and Wet Bulb on the X
 * Update title and labels
 * Subtract Wet Bulb from Air Temp (the number should be positive)
 * Change X Min=0, X Max=15
