GOES-8 Composites/Climatology

EXERCISE No 1
CLICK ON ANY OF THE MONTHS UNDER THE HEADING:
Costa Rica IR4 (10.7 µm) Temperature Threshold Frequency Composites

1. Find out how many images were used to estimate the frequencies.
2. In the month you have chosen, indicate the hours in which there are regions with 90 – 100 % frequency of cloud top temperatures below 0 °C ( If necessary, stop the loop and advance one frame at a time)
3. Could you say there are preferred region in which frequencies of clouds with top temperatures below  0 °C are higher? Describe.
4. Could you say there are preferred region in which frequencies of clouds with top temperatures below 0 °C are lower? Describe.
5. How does the position of the regions in questions 2 and 3 change with the hour of the day?

WITHOUT CLOSING THE LOOP YOU ARE VIEWING, RETURN TO THE PAGE WITH THE LOOP MENU AND CLICK ON ANOTHER MONTH, SAME YEAR

6. Is there a significant difference on the high/low frequency areas? (you can compare loops by omitting images in the loop to make it shorter, or by synchronizing the loops. To synchronize the loops keep one of the loops running, stop the other and restart it trying to match the image number with the other loop)

NOW CLOSE ONE OF THE LOOPS AND OPEN THE LOOP OF THE SAME MONTH, DIFFERENT YEAR.

7. Can you make climatological conclusions about the years you are viewing?
