  • Page 98: Appendix I: Atmospheric Correction Formula And Chart(Just For Reference)

    Appendix I: Atmospheric correction formula and chart(Just for reference) Factory setting: temperature: 20℃, pressure:1013hpa, 0ppm The correction: Kpt＝274.417-0.2905*p/(1＋0.0036*t) Where: p--Pressure value (hPa) t--Temperature value (℃) Kpt--Atmospheric correction (ppm) Example: t=20℃, p=1013hpa, L0=1000m. Then: Kpt=0ppm L=L 0 (1+Kpt)=1000×(1+0×10 -6 )=1000.000m The atmospheric value is obtained easily with the atmospheric correction chart.
