“…The Dust Characterization, Risk Assessment and Environment Analyzer on the Martian Surface (DREAMS) instrument onboard the ExoMars 2016 surface lander (Bettanini et al 2014) was designed to shed light on dust-lifting processes, but it was unfortunately lost during descent. Windblown sand, or 'saltation,' causes wind erosion and ejects dust aerosols into the Martian atmosphere through impact of saltating particles on the ground (Greeley and Iversen 1985;Almeida et al 2008).…”

We analyze the complete set of in-situ meteorological data obtained from the Viking landers in the 1970s to today's Curiosity rover to review our understanding of the modern near-surface climate of Mars, with focus on the dust, CO 2 and H 2 O cycles and their impact on the radiative and thermodynamic conditions near the surface. In particular, we provide values of the highest confidence possible for atmospheric opacity, atmospheric pressure, near-surface air temperature, ground temperature, near-surface wind speed and direction, and near-surface air relative humidity and water vapor content. Then, we study the diurnal, seasonal and interannual variability of these quantities over a span of more thanThe original version of this article was revised because due to an unfortunate turn of events a wrong value was published in Table 1. The resolution of the PHX pressure sensor was published as "0.1 mbar" whereas this value has now been corrected to "0.1 Pa" which is the correct value and should be regarded as the final version by the reader.

“…In March 2016, the ExoMars space mission was launched, and it will deliver a lander (EDM Schiaparelli ) to the surface of Mars in October of the same year. Schiaparelli includes, as the only payload operating at the surface, the meteorological station DREAMS [ Esposito et al , , ; Bettanini et al , ], which hosts six sensors for the measurement of the wind, temperature, pressure, RH, solar irradiance, and electric field. The station is expected to land in the Terra Meridiani region during the dust storm season.…”

Mineral dust particles represent the most abundant component of atmospheric aerosol in terms of dry mass. They play a key role in climate and climate change, so the study of their emission processes is of utmost importance. Measurements of dust emission into the atmosphere are scarce, so that the dust load is generally estimated using models. It is known that the emission process can generate strong atmospheric electric fields. Starting from the data we acquired in the Sahara desert, here, we show for the first time that depending on the relative humidity conditions, electric fields contribute to increase up to a factor of 10 the amount of particles emitted into the atmosphere. This means that electrical forces and humidity are critical quantities in the dust emission process and should be taken into account in climate and circulation models to obtain more realistic estimations of the dust load in the atmosphere.

“…The 2014 West Sahara Campaign depicted in has also been the opportunity to test the Micro-ARES electric field sensor of the DREAMS (Dust Characterisation, Risk Assessment, and Environment Analyser on the Martian Surface) science package for ExoMars 2016 (Bettanini et al 2014). The instrument is based on the Relaxation Probe principle (Berthelier 2000, Molina-Cuberos et al 2010) which requires a more complex post-processing than a classic field-mill sensor.…”
