Aerosol direct effect

(chairs Clarke/Heintzenberg)


Email message from Prof. Antony Clarke:

"Dear Colleagues

I about a week I leave for Prague and then to Utrecht. I will arrive late on the first day just in time to summarize the C-130 effort. I need you help in advising me of the status of your data for the C-130 briefing update.

I have 4 requests - Please respond this week before Aug 29.

1. Please email a very brief (suitable for table synopsis) the following info:

Name(s)
Instrument(s)/Parameter(s) measured(s)?
FOR EACH INSTRUMENT ESTIMATE:
Number or frequency of measurements?
Number of flights operational?
Estimate % of time your data are GOOD?
Key successfull observations?
Surprises/New Findings?
Data Analysis status (not started, 20%, 40%, 60%, 80%, Done)

2) Please reconfirm your intention for a contribution(s) at Utrecht, presentation or poster and summarize it in 100 words or less.

3) If you are indicated as a presenter below based upon your earlier input - please confirm that you will be able to do so. NOTE: I have not had my suggested presentation scheme confirmed by organizing committee at this point however I suggest preparing for a 10-15 min talk.

4) Since I will arrive late to the first day meeting it would be helpfull if you have a figure or so for an overview presentation. If you have one that you can send or make available in electronic form now - please do so. If not, please try and get it to me at the meeting as soon as you can and I will try incorporate it. Please have it as clear and self explanatory as possible.

Thank you for your prompt help and see you in Utrecht!

Tony
