FUTURE WORK IDEAS

Page 25: CAVIAR Meeting

Future Work• Assessment of Line Intensities

– Camborne • Completed; retrieved “a” are consistent with previous work

– Jungfraujoch• Work has began; will be fairly quick with confirmed water profiles. Initial results are quite

promising– Write up

• Already began writing this up as a paper....

• Absolute Calibration– Camborne

• On going work; need to think in some detail now what is causing difference between model and observations (line lists, continuum model, Kurucz , water profiles.........)

– Jungfraujoch• No Work Yet
