  Rover Environmental Monitoring Station Data - CERTIFIED
Aug 7, 2012 (Sol 1, Ls 151.0, MY 31) to March 3, 2023 (Sol 4133, Ls 31.6, My 37)[ongoing]

The Rover Environmental Monitoring Station (REMS) is MSL's primary meteorological instrument. It has been designed to record six atmospheric parameters: wind speed/direction, pressure, relative humidity, air temperature, ground temperature and ultraviolet radiation. All sensors are located around three elements: two booms attached to the rover Remote Sensing Mast (RSM), the Ultraviolet Sensor (UVS) assembly located on the rover top deck, and the Instrument Control Unit (ICU) inside the rover body. For more information regarding these parameters, see the links below.

REMS has a measurement cadence of 1 Hz and typically takes 5 minute samples every hour as well as additional 60 minute samples distributed through each sol.

Data Set Description Document

REDUCED DATA - Volume Directory containing the RDR data files for sols 1-3778 (pressures in pascals, temperature in Kelvin, etc.)


ADR Data Set Description Document - The REMS ADR data set contains ancillary data used in the processing of REMS data.

TEL Data Set Description Document - The REMS TELRDR data set contains processed REMS data where the counts given by the analog/digital converters from the instrument sensors have been converted to their corresponding thermal and electrical values.

ENV Data Set Description Document - The REMS ENVRDR data set contains processed REMS data converted to environmental magnitudes.

MOD Data Set Description Document - The REMS MODRDR data set contains processed REMS data converted to environmental magnitudes and corrected by factors having an influence in the measurements.
UVRDR (Corrected UV Fluxes RDR): This RDR contains only data coming from the UV Sensor, using an alternative processing to data found in the MODRDR. This alternative processing corrects UV fluxes for dust deposition over the sensor and inaccuracies in the original calibration function for solar zenith angles < 55.
