Lightning Imaging Sensor data is processed daily. The browse products are GIF images showing a graphical representation of the LIS orbit data for each day. Quality Control steps are taken on daily files and are released one month at a time. The QC steps produce some delay in the release of the data. To see small preview images for one month of LIS browse products, select the [Thumbnails] option corresponding to the month and year you want. If you have a slow connection or already know which day or days you want, and do not want the preview images, select the [text] option instead, and you will get a text-only calendar for that month. You may now query the data through the browse images. Click on a location to see a zoomed view of that region. Or you may choose to look at a particular orbit. To see QC data from previous months, go to the LIS Quality Controlled data page. Here is an explanation of the images NOTE: We are sorry, but non-QC data is not orderable. 2001 December [thumbnail] 2002 January [thumbnail]
