Data Status: These profiles are directly from the field and are posted as PRELIMINARY. Data Policy: We request that a proper acknowledgment to the "NOAA Earth System Research Laboratory Chemical Sciences Division" accompany the use of this data in any publications and presentations. If the use of this data in a publication constitutes a major or reasonably significant aspect of an article, co-authorship by an ESRL scientist is appropriate; please discuss any such planned use with the contact scientists. We welcome collaborations and will lend our scientific expertise in interpretation and evaluation of the data. Questions?
