Rover Environmental Monitoring Station (REMS) is a weather station on Mars for Curiosity rover contributed by Spain and Finland.{{Cite web |url=http://www.marsdaily.com/reports/Spain_Supplies_Weather_Station_For_Next_Mars_Rover_999.html |title=Spain Supplies Weather Station for Next Mars Rover - Marsdaily |access-date=2012-08-10 |archive-date=2022-03-27 |archive-url=https://web.archive.org/web/20220327174425/https://www.marsdaily.com/reports/Spain_Supplies_Weather_Station_For_Next_Mars_Rover_999.html |url-status=live }} REMS measures humidity, pressure, temperature, wind speeds, and ultraviolet radiation on Mars.{{cite web |publisher=Pierre und Marie Curie University |url=http://www-mars.lmd.jussieu.fr/paris2011/abstracts/gomez-elvira_paris2011.pdf |title=Rover Environmental Monitoring Station for MSL mission |work=4th International workshop on the Mars Atmosphere: modelling and observations |date=February 2011 |accessdate=2012-08-06 |archive-date=2021-02-24 |archive-url=https://web.archive.org/web/20210224175745/http://www-mars.lmd.jussieu.fr/paris2011/abstracts/gomez-elvira_paris2011.pdf |url-status=live }} This Spanish project is led by the Spanish Astrobiology Center and includes the Finnish Meteorological Institute as a partner, contributing pressure and humidity sensors.{{Cite web |url=http://yle.fi/uutiset/finnish_technology_lands_on_mars/6244215 |title=Finnish technology lands on Mars - UUTISET |date=6 August 2012 |access-date=2012-08-10 |archive-date=2016-03-23 |archive-url=https://web.archive.org/web/20160323224317/http://yle.fi/uutiset/finnish_technology_lands_on_mars/6244215 |url-status=live }}
Overview
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. Goals include understanding Martian general circulation, microscale weather systems, local hydrological cycle, destructive potential of UV radiation, and subsurface habitability based on ground-atmosphere interaction.{{cite web |url=http://msl-scicorner.jpl.nasa.gov/Instruments/REMS/ |archive-url=https://web.archive.org/web/20090320125448/http://msl-scicorner.jpl.nasa.gov/Instruments/REMS/ |url-status=dead |archive-date=March 20, 2009 |title=MSL Science Corner: Rover Environmental Monitoring Station (REMS) |publisher=NASA/JPL |accessdate=September 9, 2009 }}{{cite web|url=http://mars.jpl.nasa.gov/msl/news/pdfs/MSL_Fact_Sheet-20100916.pdf|title=Mars Science Laboratory Fact Sheet|publisher=NASA/JPL|accessdate=June 20, 2011|archive-date=June 26, 2019|archive-url=https://web.archive.org/web/20190626160255/https://mars.jpl.nasa.gov/msl/news/pdfs/MSL_Fact_Sheet-20100916.pdf|url-status=live}}
By August 18, 2012, REMS was turned on and its data was being returned to Earth.{{Cite web|url=http://www.cbsnews.com/8301-205_162-57495920/curiositys-mars-travel-plans-tentatively-mapped/|title=Curiosity's Mars travel plans tentatively mapped - CBS News|website=CBS News |date=August 18, 2012|archive-url=https://web.archive.org/web/20120818210500/http://www.cbsnews.com/8301-205_162-57495920/curiositys-mars-travel-plans-tentatively-mapped/ |archive-date=18 August 2012 }} The temperature at that time was 37 degrees Fahrenheit (2.8 degrees Celsius). On August 21, 2012, one of two anemometers returned data with errors. After testing it was concluded that it was broken, probably hit by a rock on descent.{{Cite web |url=http://translate.google.nl/translate?hl=nl&sl=es&tl=en&u=http%3A%2F%2Fesmateria.com%2F2012%2F08%2F21%2Fel-sensor-de-viento-espanol-de-curiosity-se-estropea%2F |title=Materia - El sensor de viento español de 'Curiosity' se estropea (Google Translate) |access-date=2012-08-21 |archive-date=2016-03-04 |archive-url=https://web.archive.org/web/20160304113321/http://translate.google.nl/translate?hl=nl&sl=es&tl=en&u=http%3A%2F%2Fesmateria.com%2F2012%2F08%2F21%2Fel-sensor-de-viento-espanol-de-curiosity-se-estropea%2F |url-status=dead }} Martian winds can still be detected with the other sensor.

The pressure sensor can detect pressures from 1 to 1150 Pa (Pascal) (0.000145038 PSI to 0.1667934 PSI).{{Cite web|url=http://an.rsl.wustl.edu/mer/help/Content/About%20the%20mission/MSL/Instruments/REMS.htm|title=Rover Environmental Monitoring Station (REMS)|website=an.rsl.wustl.edu|language=en-us|access-date=2018-01-24|archive-date=2016-12-20|archive-url=https://web.archive.org/web/20161220110256/http://an.rsl.wustl.edu/mer/help/Content/About%20the%20mission/MSL/Instruments/REMS.htm|url-status=dead}} For comparison, 1 atmosphere is 101,325 Pascals or 14.7 PSI.{{Cite web|url=http://www.ilpi.com/msds/ref/pressureunits.html|title=The MSDS HyperGlossary: Pressure Unit Conversions|website=www.ilpi.com|access-date=2018-01-24|archive-date=2022-02-14|archive-url=https://web.archive.org/web/20220214235115/http://www.ilpi.com/msds/ref/pressureunits.html|url-status=live}}
The air temperature, wind speed and direction sensor for InSight Mars lander (planned for 2018 launch) is based on REMS, also contributed by Spain.{{Cite web | url=http://sites.nationalacademies.org/cs/groups/ssbsite/documents/webpage/ssb_086912.pdf | title=InSight: A Geophysical Mission to a Terrestrial Planet Interior| archive-url=https://web.archive.org/web/20170315145741/http://sites.nationalacademies.org/cs/groups/ssbsite/documents/webpage/ssb_086912.pdf | archive-date=2017-03-15 }}
