Hi Bei, re: > When I receiving the cosmicrt profiles using ldm, the filename of a profile > contains the UTC time of that RO event, right? No, not necessarily. The pqact.conf action I sent you previously matches the date/time information in the Product ID. If the date/time information in the Product ID reflects the date/time of the data in the product, then the answer would be yes. I can't say if this is the case since it is the Cosmic folks who create the Product IDs for the products being made available by the LDM/IDD. re: > But I thought it is supposed to be event-driven and real time. The LDM/IDD is event-driven. Whether or not the products being sent are real-time or not depends on what the originators of data setup. The typical use of the IDD is to relay real-time data, but any data can be sent. re: > So, to my understanding, when Calgary time is 11:00 am while UTC is 18:00 > pm, so I can receive profiles in 18:00pm if at that moment an event happens, > right? It depends on what the Cosmic folks are doing. If they are making real-time data available in real-time, then you should receive it in real-time. If, on the other hand, they decide to delay the sending of products by some seconds/minutes/hours/days, then the data will not be real-time. What you can count on, however, is that the LDM will send the data as soon as it is available. re: > But according to the saved filename, I found it is not real time, > for example, the latest event-driven data I received in Calgary time > 11:00 am (I staring at screen and wait for data stream....), is from > UTC 14:12~17:08 > > Mar 11 18:00:16 pqutil INFO: 12536 20110311180006.084 EXP 000 > /pub_out/cosmicrt/level2/ionPrf/2011.070/ionPrf_C005.2011.070.14.12.G20_0001.0001_nc > Mar 11 18:00:16 pqutil INFO: 12872 20110311180006.520 EXP 000 > /pub_out/cosmicrt/level2/ionPrf/2011.070/ionPrf_C005.2011.070.14.18.G32_0001.0001_nc > ... This would suggest that the Cosmic folks are delaying the sending of the data. re: > So, could you please explain the real time thing of cosmicrt profiles? You will need to contact the Cosmic folks for an accurate explanation. All I can say is that the products are being relayed by the LDM as soon as they are made available to the LDM. re: > And if certain data processing time is required to generate those > profiles, how long it will cost? Again, this is a question for the Cosmic folks.
