Hello Ansley,
Thank you for the response.
I have a preliminary installation of LAS v8.0 that we are testing out for another project. When all goes well with that installation and configuration then we will upgrade our PO.DAAC LAS server.
How much of an effort is it to update the precision in LAS 7.3 code?
Thanks,
Rosanna.

Hi Rosanna,
This isn't something that's directly configurable. I put the dataset into a LAS V8 server, where we've made a small change to the ASCII and CSV listings to show one or two more decimal places in the variable listed. Here's the start of a CSV listing of a line
in longitude:
Total Number of Records 32.
DATA SET: http://thredds.jpl.nasa.gov/thredds/dodsC/GHRSST_NCDC-L4LRblend-GLOB-AVHRR_AMSR_OI_TIMEAGG/aggregate__ghrsst_NCDC-L4LRblend-GLOB-AVHRR_AMSR_OI.ncml
X: 0.5 to 32.5
Column 1: DATETIME is Time String BAD FLAG : -1.E+34
Column 2: TIME is Time Coordinates (seconds since 01-JAN-1981 00:00:00) BAD FLAG : -1.E+34
Column 3: LON is Longitude (degrees_east) BAD FLAG : -1.E+34
Column 4: LAT is Latitude (degrees_north) BAD FLAG : -1.E+34
Column 5: ANALYSED_SST is analysed sea surface temperature (kelvin) BAD FLAG : -1.E+34

153.9E 295.71
154.1E 295.62
154.4E 295.75
154.6E 295.76
154.9E 295.67
155.1E 295.51
Would that be adequate? If you can update to LAS V8, you'd get this, or it is a change I could help you make in the LAS v7.3 there at jpl.

Hello there,
How can I configure LAS so that a variable that is originally of 16 bit Interger type return (ASCII or CSV) values to 2 decimal places after the scale factor and add_offset are automatically applied when a user select any of the options:
[Show Values]
[Save As - (ASCII or CSV)]
select
Ocean Temperature
- GHRSST Level 4 AVHRR_OI Global Blended Sea Surface Temperature
- - analysed sea surface temperature
Thanks so much,
Rosanna.
