MTRDR DATA

[PRIYANKA]

Hello sir,

I am Priyanka Kumari currently working on mineral mapping using CRISM Data. I want to know why MROCR_40001 (MTRDR DATA) Is not available after 2012?

I need recent mtrdr data for my current research.

can you please help to get MTRDR data from 2015 to 2021?

Priyanka,

Unfortunately the CRISM team has no plans to produce MTRDR products for CRISM observations acquired past May 21, 2012. The current processing that creates the MTRDRs also does VNIR/IR data joining and browse product generation using information from EPF sequences. Once the scanning gimbal started experiencing issues (limited or no EPF sequences), and especially after the IR heaters died (no IR data), using the current processing on those subsequent images became impossible.

Thankyou for this information sir.

So in this case which data product we should use to understand the current scenario of martian surface?

Hi: I would use the TRR3 data sets and the CRISM Analysis Tool that works with ENVI. Are you using ENVI?

thankyou for the information sir

yes sir I am using the CAT tool using ENVI software.

TRR3 data set has FRT(Full Resolution Target) file till 2012  but after that hsv. file (Multispectral data) is present till 2020.

So, why hyperspectral data is not available after 2012?

I just searched the Mars Orbital Data Explorer and there are hundreds of FRT observation from 2012 until now. Look for TRR3 TRDRs and FRTs and/or ATOs. Please read the CRISM Software Specification Document to become familiar with CRISM products https://pds-geosciences.wustl.edu/mro/mro-m-crism-2-edr-v1/mrocr_0001/document/crism_dpsis.pdf
