When configuring the plugin it is possible to do a quick test to see if the satellite data is online available (requires internet
connection). If the light after ‘Ozone value valid’ stays red, connection to the satellite data could not be made. The data from
the TOMS satellite is available until December 2006. After that data the satellite stopped providing data. The OMI satellite data
is also available after that date.

The location of the OMI data on the internet is:

ftp://toms.gsfc.nasa.gov/pub/omi/data/ozone/ followed by the year and day string.

The default setting for the provided plug-in is for TOMS data. An example of the Ozone plug-in for OMI data is given below.

Example

On this page the input data formatting configuration must be entered. The program can read UV data from many types of files.
Characteristics of files that can be read are:
• It is a text file
• It has 0 or more header lines
• Data appears in columns
• It has date and time column(s)
• It has a UV Data column
• Optionally it has a Temperature Data column
• The date and time column(s) appear before the UV and Temperature Data columns
• Uses dot as decimal separator

6.4.1 Time Zone Offset

Time Zone Offset specifies in what time zone measurements have been recorded. It is important to enter a correct number for
Time Zone Offset, so the program can calculate the right solar zenith angle and find the appropriate ozone value for each meas-
urement. See Time Handling for more details about time.

6.4.2 Date Time Format

Date Time Format specifies how date and time are extracted from the measurement files. See Date and Time Pattern Matching
Characters for characters that can be entered and what they mean.
