Rich,
Thats the same problem I have. I can’t move the file into your account. Lets
have TC give us sudo to each other’s accounts.

Hi Russ,
Thanks for tracking this down. I don't have permission to copy the new file
over to McIDAS20201. Do you have that permission? If so could you do that?
If not, I guess I'll have to get TC to do it.
Thanks,
Rich

Rich,
YUP that was the problem all along. the server was reading the
Cloud_Mask_SPI file instead of the Cloud_Mask file. I have placed updated code
in my account on neige in ~russd/xrd/src. The file is
modxaget.cp
Copy this module into your McIDAS2020.1 /src directory (replacing the
modxaget.cp that currently resides there)
Run the McIDAS 2020.1 .sh script to make and install the new code

Rich,
The server is reading the Cloud_Mask_SPI dataset. I’m guessing that it
should be reading the Cloud_Mask dataset. What is this SPI variant?

The mask is a byte array, 6X2030X1354. McIDAS bands 1-30 except bands 2 and 6
are represented by one bit each of the 48 per pixel. Band 2 (basic output
mask) is a 2-bit value (value=0-3) as is Band 6 (scene type). Band 31 (250-
mask) is displayed at 4 times the resolution of the other bands and is created
from the remaining 16 bits (33-48).

Weird!? For all of the other bands they resolve as 1 byte values (HDF type 20 =
Int8) but band2 comes back as a 2byte value (type 22 = Int16). AND the
dimension order is different for band2. Again, For all the other band Is get 3
dimensions (6X2030X1354). For Band2 I get 3 dimensions but the order is
2030X1354X2. This is why I asked for the dump. That will tell me the internals
of Band2.

Just to be clear, that's single byte values, not 2-byte.

In the MODIS cloud mask (MxD35_L2) data, both mask and QA are byte values.

Rich,
No problem.
Thanks for the dump. That might clear up some mysteries. The Band2 imagery
appears to be INT16 (2byte values) from what I can tell without the dump. Is
that correct?

Hi Russ,
Sorry, I took a Covid day yesterday ...
On neige, use ~richardf/bin/ncdump -h.

Do you have access to a ncdump exe? I need a
ncdump -h
for the test file that you supplied to me. Looks like there are some
differences between Band2 in these files. I need some info on how this band is
read and how the Qual Flag is applied.
