Example 1:

if you would like to access data for Millstone Hill Fabry Perot you would do the following:

  1. From the Data Services page click on Get/Plot Data.
  2. Click on the 'Data' tab towards the top of the page
  3. And now you can start the way you usually start on the CEDAR web
  4. Let's start by selecting the instrument ... click on 'Start by Instrument'
  5. Click on the pulldown menu 'Filter by Physical Domain' and select 'Upper Earth Atmosphere (CEDAR)'
  6. Or ... to make it even easier, click on the pulldown menu 'Instrument Type' and select 'Optical Instrument > Interferometer'
  7. You can also click the checkbox 'Show Instrument Code' and click on 'Reload'
  8. Now, form the list, select instrument '5340 – Millstone Hill Fabry Perot' and click on 'Next'
  9. Note the question marks here and there. If you click on them you can get more information about whatever that question mark is next to. For example, in the left box you'll see the instrument you've just selected and there's a question mark next to it. Click that question mark.
  10. Select the date range for your query. I'm selecting 1992, Month 04, Day 02, and leaving the default # Days to 10. Click 'Next'.
  11. Now you'll see some familiar links for 'TAB', 'FLAT', 'INFO', 'DAS', 'DDS', 'OPeNDAP', 'STREAM', and 'IDL'. Go ahead and click on 'TAB'.
  12. If you aren't already logged in to the portal you will now see a login screen. Use your CEDAR username and password.
  13. Now you should see the tabbed data.
  14. You can click the back arrow on your browser to select a different format, such as 'DDS' or get the data by clicking 'OPeNDAP'.

In order to plot some data let's do a little more selection. After clicking the back arrow you will again see the screen with 'TAB', 'FLAT', etc... Below that you will see the list of parameters. Let's select a few.

  1. Click the check box 'Show Parameter Codes', if not already checked, and click 'Reload'.
  2. Select the parameters 810, 1410, and 1420 and then click 'Next'.
  3. You will now see a screen with the 'TAB', 'FLAT', etc... links. Right below that you will see Data Plots and the selection 'Time Series'. Click on 'Time Series'.
  4. You should now see the plot of the three parameters 810, 1410, and 1420.
