From: OKA Eitarou [mailto:eoka@ori.u-tokyo.ac.jp] Sent: Monday, July 24, 2006 2:20 PM Subject: North Pacific Argo float data: An Important Notice Dear "North Pacific Argo float data set" users, I have recently stopped updaing my dataset, due to a trouble in downloading the original data from Argo Global Data Centers started in association with the data format change in March 2006, but resumed today. The data of May and June 2006 are now avaibable. Please use them. http://ocg.ori.u-tokyo.ac.jp/member/eoka/data/NPargodata/ IMPORTANT NOTICE: I have found some floats with a wrong sequence of profile numbers in the June 2006 data (please refer to the attached "bad_prof_num.txt" in which a sequence of profile numbers and dates are shown for each float). The data from these floats were processed through the AO (AOML, USA) data center. For each of the floats, the profile number jumps and almost doubles around the mid-month, and increases by 2 each time after that. The reason is unknown, but it is not likely a mistake in our data processing. We WILL NOT correct these bad profile numbers. The reason is that the profile numbers are originally not perfectly precise. For example, the profiles processed through GT (GTS) don't have a profile number. Also, some (the percentage is very small) of the profiles from other data centers have wrong a profile number. (For example, WMO ID 2900416: the profile took on Apr 28, 2006 should have a profile number of 67, but has 83 instead.) Therefore, I WOULD REQUEST that for the order of profiles for a particular float, you refer to the observation date, not the profile number. Please ask me if you have any question. thank you, Eitarou -------------------------------------------------------------------- Attached file "bad_prof_num.txt" WMO: 2900371 102 20060602 103 20060607 104 20060612 209 20060617 211 20060622 213 20060627 WMO: 2900366 125 20060602 126 20060607 127 20060612 255 20060617 WMO: 2900365 125 20060602 126 20060607 127 20060612 255 20060617 WMO: 2900378 28 20060601 29 20060606 30 20060611 61 20060616 63 20060621 65 20060626 WMO: 2900379 28 20060601 29 20060606 30 20060611 61 20060616 63 20060621 65 20060626 WMO: 2900382 10 20060601 11 20060606 12 20060611 25 20060616 27 20060621 29 20060626 --------------------------------------------------------------------
