Quantum yield in photosynthesis is the moles of CO2 fixed per mole of quanta (photons) absorbed, or else the efficiency with which light is converted into fixed
carbon. Typically about 0.06 moles CO2 are fixed per mole of quanta under favorable conditions (and normal (ambient) CO2 concentration).
Quantum yield is the slope (of the linear part)of the light-response curve based on absorbed light.

quantum yield is define as follows
Q=number of photo chemical product/Total number of quanta absorbed

The slope of the of the light-response curve must be fitted to the truly linear region, where the intial Kok-effect is absent, where the lowest permissable PAR step likely depends on species and other factors.

I need to monitor spatial distribution of trace gases and ozone layer on asia. Data sets available on
comes in he5 formate. I need to convert this format to Erdas img or geoTIFF format to analyse it (as i have command on it). Please suggest any suitable method of conversion using any software or elsewise please guide me of any software which can be used to directly read/analyse he5 formate.
