2. About MAVEN data MAVEN has been taking data at Mars for ~15 months
Three instrument suites:
Particles & Fields (SWEA, SWIA, SEP, STATIC, LPW, MAG, EUV)
Remote Sensing (IUVS)
NGIMS
Data has been released to the public:
Currently released up through November 15, 2015
New releases occur every three months and cover 3 months
Next release: mid-May, will include Nov 2015 – Feb 2016

3. Data types Instrument data formats: Other data: IUVS: FITS NGIMS: CSV
Particles & Fields: CDF, except MAG = ASCII.
Other data:
Key Parameter (KP) data:
ASCII tables containing specific parameters
Two types: in situ + IUVS
Accelerometer
Ancillary & Events
SPICE

4. Data levels In general: IUVS is the exception:
Level 0 = binary telemetry packets
Level 1 = intermediate processing products
Level 2 = calibrated science data products
Level 3 = derived, resampled, etc.
IUVS is the exception:
1b: calibrated images
1c: spatial/spectral binning, smoothing
2: profiles & maps of densities & column abundances

5. MAVEN on the Planetary Data System
Planetary Plasma Interactions (PPI)
All PF: SWIA, SWEA, SEP, STATIC, LPW, MAG, EUV
In situ Key Parameters
Ancillary
Atmospheres
NGIMS
IUVS & IUVS KP
Accelerometer

6. The MAVEN Science Data Center (SDC)
Central repository for all MAVEN data
Data and documentation for all instruments
Multiple ways of accessing data
Preview data:
Interactive plots of MAVEN Key Parameters
PF Level 2 summary plots
Data access & visualization software
Data availability information
Mission events list

7. Pages for each dataset Documentation Caveats
Links to the individual files
Links to compressed tar files

8. Ways to get data from the SDC
Dataset pages: compressed collections available
Search: find data by instrument, date, and level
Browse the SDC’s storage for individual files
For best results: Use the same directory structure as the SDC

9. The MAVEN DIViDE Toolkit
IDL software for downloading and working with MAVEN data and models.
Available on the SDC website under “Software,” with documentation & tutorials, including videos.
Downloading data:
Easily download Key Parameter and Level 2 files
Will search for files that you don’t already have
Working with data
Loads Key Parameter data into IDL structures
2D and 3D plots of data; overlay on map or globe

13. Reading material Instrument “SIS” documents
“Software Interface Specification”
Contains information about the instrument, how data was collected and processed, and how data is formatted and organized.
