Linux Server snow

• Snow Hardware Overview

• 3 nodes each with 32 AMD Opterons (2.3 GHz) and 128 GB RAM
• snow1 and snow2 for interactive use, snow3 for batch processing

Directory structure

The following structure under /scratch/clisap/seaice shall be used if applicable:

• SENSOR/LEVEL/HEMISPHERE/YEAR/MONTH/DAY for the incoming satellite data (radiances).

• OWN_PRODUCTS/PRODUCT_NAME/HEMISPHERE/YEAR/MONTH/DAY for the own derived products (final results)

• TMP/uxxxxx/ for intermediate (temporary) data

HEMISPHERE should be set to NORTH or SOUTH if applicable. For example, this is not the case for AMSR-E L1A swath data but for gridded data (L3)

Data Level

• Level 0 (L0) are the raw observational data.
• Level 1 (L1) are the calibrated radiances on a swath basis.
• Level 2 (L2) are the derived products on a swath basis.
• Level 3 (L3) are the derived gridded products.

Backup

Please note that there is no backup. Original data shall be stored elsewhere.

Permissions

As the data are used by the whole seaice group the permissions should be granted. You can use chmod -R g+rw DIRECTORY/ to set the permissions recursively for a directory.
