2. Part 1a: Instructions Now that you have downloaded the PowerPoint file, please read the Instructions in Parts 1a (this slide) and familiarise yourself with the Learning Outcomes in slide 1b (next slide) Print out the Worksheet in Part 2a of this file (if applicable) Examine the Pre-activity Resources in Part 2b of this file (if applicable). Download the appropriate accompanying Video Recording (.wmv file). The recording is typically of 3-13 minute duration. Commence listening to the Recording. Pause the Recording whenever you want to annotate notes on the Worksheet. You may wish to examine the slides in Part 3 of this file in Slideshow mode when you stop the Recording. Note that Rapid Scan imagery in the animations embedded in the PowerPoint slides is often clearer than in the Recording. Towards the end of the recording, recommended answers for the exercises are sometimes given.

3. Part 1b: Learning Outcomes At the end of this exercise you will: Have a better understanding of how 10 minute rapid scan satellite data is used by Operational Forecasters for monitoring, nowcasting and short- term forecasting of fog and low cloud, both during the night time and during the day. Have a better understanding of the advantage of using Rapid Scan data over existing hourly satellite image data for the monitoring, nowcasting and short term forecasting of fog and low cloud, both during the night time and during the day. Be able to verify fog/low cloud using other meteorological data (ie. ceilometer). Note – corresponding WMO-1083 Capabilities and BOM Enabling Skills are given on the link "Underpinning WMO-1083 Capabilities and BOM Enabling Skills" on the National Himawari-8 Training Campaign homepage.
