MODICE for tile h23v05, all of 2001 (244-344), comparing affects of cleanse bug fix, addition of snow/other destriping, and switch from MOD10A1 clouds to MOD09GA clouds.
First row is just MODICE output at each step of the way, gray=ICE, yellow=NEVER_SEEN. Data are h23v05, 2001 (sep1-nov30).
| Original: cloud=MOD10A1, cleanse bug, no destriping |
cloud=MOD10A1, cleanse bug fixed, no destriping |
cloud=MOD10A1, cleanse bug, destriping |
cloud=MOD10A1, cleanse bug fixed, destriping |
cloud=MOD09GA, cleanse bug fixed, destriping |

Next row is a series of differences. Legend: white=MODICE in both, red=MODICE in before but not after, blue=MODICE in after but not before; green=never_seen in before, changed to MODICE after
I'm surprised that there isn't more green in the original MOD10A1 vs latest fixes MOD09GA. But maybe Tom isn't? Remember that this is MODICE, so it's a cumulative effect of differences over the 90 days. I think the bug fix and destriping are more important, at least for this tile.
| cloud=MOD10A1; before=original, after=cleanse bug fix |
cloud=MOD10A1; before=original, after=destriping |
cloud=MOD10A1; before=original, after=cleanse_bug fix & destriping |
before=original+cleanse fix+destriping, after=all fixes and MOD09GA clouds (this is just the effect of MOD10A1 vs. MOD09GA clouds) |
before=original, after=all fixes and MOD09GA clouds |
