9 SETTING ATMOSPHERIC CORRECTION

Atmospheric Correction Chart (For your reference)

The atmospheric correction value is obtained easily with the atmospheric correction chart. Find the

measured temperature in horizontal, and pressure in vertical on the chart.

Read the value from the diagonal line, which represents the required atmospheric correction value.

Example:

The measured temperature is +26°C

The measured pressure is 1014 hPa

There fore,

The correction value is +10ppm
