MODIS products have been mentioned in NWS Area Forecast Discussions 151 times Liam Gumley, SSEC UW-Madison

22 Space Science and Engineering Center University of Wisconsin-Madison LANCE Latency How critical is the 3-hour latency to your application(s)? Not critical currently. Would you application benefit from reduced latency and, if so, what latency would be desirable? Volcanic ash global retrievals would benefit from reduced latency. Can you identify new applications that are not presently serviced by LANCE if the latency could be reduced? No. Liam Gumley, SSEC UW-Madison

23 Space Science and Engineering Center University of Wisconsin-Madison Comments on the Present LANCE System (1 of 2) Are there any features of the present system that you find particularly useful? FTP access. Do you make use of the LANCE website, and, if so, what pages do you find particularly useful? No. Have you received adequate information concerning the status of the system and system changes? Yes. Liam Gumley, SSEC UW-Madison

24 Space Science and Engineering Center University of Wisconsin-Madison Comments on the Present LANCE System (2 of 2) Do you have any criticisms of the present LANCE system? Have you been particularly impacted by system downtime or degraded service? For real-time applications, delayed data arrival can cause problems because the customer processing system may only be sized to handle real-time rates (e.g., 10 MODIS granules per hour). If data suddenly appears at higher rates because of delayed processing, system must churn much faster to keep up. Customer must be able to handle it (e.g., ignore data more than 12 hours older than the current time). Liam Gumley, SSEC UW-Madison

25 Space Science and Engineering Center University of Wisconsin-Madison Future Changes Do you have any suggestions for modifications or changes to the current system over the next 12 months? –Web services –Product images –MODIS NBAR real-time Can you suggest any longer-range changes? –Consider interfacing with DB sites users in a strategic way –Everyone in the DB world receives the same packets from the spacecraft… Liam Gumley, SSEC UW-Madison
