Basic Analytical Functions of Giovanni

Plot TypeDescription
Vertical profile, Parameter vs. PressureThis function displays 'Parameter vs. Pressure' vertical profile(s) for selected parameter(s), and selected single or multiple 'sunrise' or 'sunset' and event(s).
Vertical profile, Parameter vs. AltitudeThis function displays 'Parameter vs. Altitude' vertical profile(s) for selected parameter(s), and selected single or multiple 'sunrise' or 'sunset' and event(s).

Precision Estimates Option

In the HALOE data files, the error estimates are provided in the form of Standard Deviation. These numbers represent a precision estimate of the data, not an accuracy. The noise or random error, error in the solar tracking, and error in the estimation of aerosols induced uncertainty (under heavy aerosol conditions) in the retrieval of most of the species are root sum squared. For information about quality of measurements of each species, please refer to the detailed documentation produced by the HALOE instrument team.

Event Number Selections

Please check or uncheck the event number checkboxes of sunrise/sunset event type(s). Please refer to the "HALOE Event Coverage" map for the selected date while making the event number selections. Whenever the "All" is checked, it will be taken as if all the avaliable events have been selected.

Y-axis Range Options

OptionDescription
Pre-defined:Currently Y-axis range is set from 1000.0mb to 0.001mb for pressure and from 0.0km to 100.0km for altitude.
User defined:Allows user to specify the minimum and maximum pressure (in mb) or altitude (in km) for vertical profile displays. Please note that the selections for min/max pressure values will be rounded down/up to the nearest power of 10 for display. Example: selection of 50mb to 850mb will be rounded as 10mb to 1000mb.
