Abstract
The O-2((1) Delta(g)) dayglow produced at 1.27 mu m by ozone photolysi s is ideal for ground-based mapping of high-altitude ozone using long- slit high-resolution spectrographs like CSHELL, CGS4, and Phoenix. Cou pled to mapping H2O at 1.13 mu m and CO and CO2 at 1.57 mu with the sa me instruments, it is possible to map hygropause using the rotational temperatures of CO2 and O-2((1) Delta(g)). Strong seasonal variations of hygropause (from 10 to 40 km) and associated variations of high-alt itude ozone (by an order of magnitude above 20 km) are important novel concepts which may be studied in detail by these observations. Showin g even greater promise is the combination of O-2((1) Delta(g)) dayglow mapping with mapping of water abundance and temperature profiles by t he thermal emission spectrometer onboard the Mars Global Surveyor. A l ist of problems which may be solved or improved upon by these observat ions is included.
