Meteorology 301 - Lab 10

Introduction

GOAL:
1. Place some examples of your work into your student portfolio page.
2. Give your examples appropriate annotation and cross links.

Instructions

1.Login to your Project Vincent account. Then, go to your directory where you are storing Matlab files. For most of you, this will probably be your "home" directory, the directory where you are when you login.

2. Create appropriate plot file

In last week's lab, you created a plot of Q vs. Ts, and saved in as a postscript file. To use the plot in a Web page, it needs to be in "gif" format. If you did not save this plot in "gif" format last week, using the -dtiff option to print to disk and XVue to convert to gif, you need to recreate the plot now. Follow these steps:

1. Go to your directory containing your Matlab files.
2. Start matlab. If you forget how, go to Lab 5 , step 4.
3. In Matlab, enter the following lines from last week's steps 5, 6 & 7:
   >>alpha=0.3
   >>for i = 1 : 71
   Ts(i) = 200 + (i-1)*2 ;
   end
   
   >>for i = 1 : 71
   Qnov(i) = Q_Ts_nov(Ts(i),alpha) ;
   end
   
   >>for i = 1 : 71
   [Qv(i),PW(i),eps(i)] = Q_Ts_v(Ts(i),alpha) ;
   end
   
4. Make your plot. Note the color choices I have prescribed:
   >>plot(Qv,Ts,'r*',Qnov,Ts,'bd')
   
5. Save the file to disk. Now use a print option that will save the file in tiff format:
   >>print -dtiff Q_Ts.tiff
   
6. exit Matlab and follow the XVue steps in Lab 9.

3.No matter when you created "Q_Ts.gif", move it now to your Web directory:

> mv Q_Ts.gif ~/WWW

Note that there is a space between "gif" and "~".

4 Link Q_Ts.gif to your portfolio.

Switch yourself to your WWW directory, which contains your personal web page file and, more important here, your portfolio file. You may find it helpful at this point to start a Web browser, so you can look at your portfolio file. Recall that it contains several categories in which students should demonstrate their capabilities. One of the categories is "Computer Programming and Modeling". We will make an entry into this category in two ways:

1. by placing your plot in it
2. by writing a caption to the plot

5. Edit your portfolio file using emacs or your editor of choice. You need to make a link in your portfolio to your plot "Q_Ts.gif". You should do it after the "--examples--" line in the portfolio. You previously made a link to a figure in Lab 4, when you inserted your photo into your portfolio. This was done using the html tag, [img src="filename"]. (Recall that the real tag uses"<" and ">" instead of "[" and "]". Review Lab 2 if you do not remember why I have to use "[" and "]" in my instructions to you.)

• Move yourself in the editor to the point at the end of the "--examples--" line under "Computer Programming and Modeling".

• Push the return button to open a new line.

• enter
  [img src="Q_Ts.gif"]
  remembering to substitute angle brackets for the square brackets.

• Save your update without leaving emacs:
  C-x C-s
  where the "C" stands for the "Control" key.

• If you have a Web browser active, you should reload your portfolio page and look at the effect of including the new link.

6. Annotate your figure

You should move the editor's cursor or point to create a new, blank line betwee the "examples" and the "img src" lines. Type at least one paragraph describing the figure below it that you just now linked to your Web page. The paragraph should say

1. What is plotted against what.
2. What type of model was used to produce each curve and what assumptions are involved in creating these models.
3. What the curves show us, each by itself and in comparison with the other.

7.What I need to see.
You do not have to hand in anything to me on this lab. Instead, I will look at your portfolio page to determine your grade for the lab. The grade will be determined by the success of your link, and the accuracy and completeness of your annotation to the figure.
