TIMAP – Thermal Inertia Map

Instrument: Thermal Emission Spectrometer

PDS Data Set ID: MGS-M-TES-5-TIMAP-V1.0 DOI: 10.17189/1519489

For more information about TES TIMAP products, see the Data Set Catalog File.

The Thermal Emission Spectrometer (TES) Thermal Inertia Map (TIMAP) data products are derived using TES thermal bolometer temperature observations taken over three Mars years from orbit 1583 to 24346 (as counted by TES), from February 1999 (beginning of mapping mission) to April 2004. Maps use only nightside or dayside data with surface temperatures between 160 and 400 K. Nightside (southbound) and dayside (northbound) maps are included and each has been infilled between 87 degrees south and 87 degrees north latitude. The derived range is 5 to 5000 J / (m2 * K * s1/2). Higher and lower values are not computed.

An interpolation mask is provided for each map, which identifies those pixels where the map has been infilled by interpolation (less than 8% in each case). If the interpolated pixels are not desired, they can be removed by multiplying the thermal inertia map by the associated interpolation mask.

Browse color images including scale bars are available in JPEG format for nightside and dayside thermal inertia maps. Large (approximately 3.3 Mb) and small (approximately 0.15 Mb) versions are included.
