Essentially, I have years 2009-2011 plus 2012 through May 13th. This gives a time series of length 1229. Then, I switch the 2012 file for one that goes through May 14th. The catalog page does not reflect this change under the "TimeCoverage:" information. However, clicking through to the opendap access shows a time series with 1230 steps. So, it seems that the data is there, but it is not being described correctly on the catalog page. This is a separate issue that we will address. I did this again this morning using the latest 4.2 download. -Lansing Ticket Details =================== Ticket ID: YRL-997326 Department: Support THREDDS Priority: Emergency Status: Open
