• What to begin with
  Open
  • In initial timepoint directories don't contain files with meteodata. You can keep files with temperature data in any directory. But it would be more convenient for you to copy data with the temperature data in "PrimaryTemperature".
  • Select a menu item "Data for calculation of pressure" and enter all required data - the geographic latitude, height above sea level and formula for calculations - Lagrange or Babin.

  
  
• Tables with meteodata
  Open
  • At first you can open only the file with primary temperature data. On its basis you can do further calculations.
  • As soon as you have made calculations, results of calculations will be automatically placed in the corresponding directories. You will be able to open any of files, having selected the corresponding menu item.
  • Meteofiles in a directory can be much. For more convenient navigation you can print number of year and mark month, then only those files which contain in the name this year and month will be shown in the list of files. Such files will be significantly less.
    Clear the entry field of number of year, mark "All" in the table of the choice of month, you will see all meteofiles which are available in this directory in the field of the choice of files.
  • Having opened the file with meteodata, you will see the table which columns represent a step on height in m, and lines - the current time in 5 minutes. An element of the table are temperature data or data on atmospheric pressure.
  • Not all columns find room on one page. You can transfer to the following page, having pressed the button on top of the table [>]. To return to the original page - [<].
  • Above the heading with the name of the open file is located.
  • In the files with data on atmospheric pressure, and also on potential temperature in every line there are two sublines : top - relative humidity 0%, lower - relative humidity 100%. Since relative humidity is unknown at the time of measurement, value of pressure will be in this interval.

In the center of the drawing there is a color field - dependence of temperature on height and time. Each difference of temperatures equal to one degree is painted in color which contains in the palette located in the lower part of the drawing.
  • Under the color field the color broken line reflecting distribution of temperature within a day in a certain height is drawn. This height is printed to the left of this drawing. On the right from the drawing you can choose any height interesting you and look at distribution of temperature at this height. Sites of a broken line with various coloring correspond to an interval of temperatures of the same color on a color palette. Choosing this or that height, you receive the schedule of dependence. You can also select the "All Heights" item and look how the schedules of change of temperature at all heights imposed at each other look.
