Meteorological station in Prague

Assignment

  1. Describe the experiment and its arrangement
  2. Specify the name the of the ISES components used in this experiment.
  3. Are you connected to the experiment alone just now, or is it not the case? If no, find the addresses of your co experimentators? Do you know where the addresses occur?
  4. Choose one of the three variables (the temperature, the pressure, the sunshine intensity), which you would like to measure. Of course you can work step by step with all of them nearly the same way.
  5. Write on the panel the wanted period e.g. for the temperature. It can be one day, one weak or month, as you like.
  6. Is it possible to choose the period of observation: a) six month, b) seven month, c) 30 weeks, d) 27 weeks, e) 200 days, f) 150 days?
  7. What is the accuracy of the temperature and the time measurements Δt; ?
  8. For the desired time interval draw the graphical representation of the selected quantity.
  9. Which variable you choose as the independent variable ( the horizontal coordinate) in your and which dependent one (the vertical coordinate)?.
  10. Notice carefully the smallest unit of independent variable in desired period.
  11. Think about the accuracy of your observations. Is it the half of the smallest unit of the scale on the graph? Or is it 1 %?
  12. You want to generate a new web page with the new table of the measured data. What do you have to do?
  13. Put the observed data in a table. Be careful about the time unit.
  14. Observe the global extreme for investigated function, e.g. in the desired time interval find the lowest temperature and the highest temperature. What can be done, if you find two or more the same value of the temperature at different time? Try to enhance the accuracy of the determination of these values by the changing the scale of time. (Chose e.g. shorter time period).
  15. Make a graph of an independent variable in the basic SI unit. What time is it?
  16. Compare the precision of the determination of the global and local extremes of temperature for different scales of time axis.
  17. Determine the average value of the temperature for the selected time period.
  18. Determine and write into a table the difference of the instantaneous and the average temperature.
  19. What can we say about the sum of all these deviations in q.19? Verify if it is equal to zero?
  20. Compare for the selected time interval and quantities the graphs for three following years and determine the global extreme and its mean quadratic deviation. Compare the results of the observed pressure, temperature and sunshine together as one body of data. Can you find any correlations or do you consider these three quantities as independent?
  21. Discus the influence of the changes of these variables on your mood and body fitness.
  22. Elaborate project, which consists of standard parts: Introduction, Theory, Experiment ( data and charts, calculations and tables) and Discussion.
In the last section discuss the results and also rate the work and measurement with the Internet.
