A prototype hygrometer was built applying these effects, and the procedure for data reduction was confirmed. We examined the feasibility of this data reduction method in the practical airbone use of the instrument in the troposphere. The results confirm the instrument can be used to measure the water vapor content not only in the stratosphere but also in the troposphere.}, pages = {239--246}, title = {A note on the new type hygrometer using the photochemical reaction: H2O+hν(Ly-α line) → OH*+H, and OH*→ OH + hν(λ=309nm)}, volume = {22}, year = {1982} }
