DESCRIPTION:Cavity ring down spectroscopy (CRDS) is an ultra-sensitive spe
 ctroscopic technique now used widely in the laboratory. However\, the evol
 ution of laboratory based equipment to function in the field environment p
 resents many formidable challenges. In this presentation the principles of
  CRDS will be outlined. Variants of CRDS - broad band CRDS and cavity enha
 nced absorption spectroscopy (CEAS)\, both representing important evolutio
 nary steps towards ultra sensitive and portable field instruments\, will b
 e described.
