Martian Atmospheric Temperature and Density Profiles During the First Year of NOMAD/TGO Solar Occultation Measurements

Cluster Analysis of Martian Atmospheric Temperature Profiles

Introduction: Cluster analysis a powerful tool to reduce a large amount of multivariate data to a few representative cases. Its most obvious application is to large data sets, such as spectroscopic remote sensing measurements of recent space experiments, as well as, cases where a huge amount of information needs to be explored in order to understand its scientific content. Marzo et al. [1] pres...

Deriving atmospheric water vapor and ozone profiles from active microwave occultation measurements

The GPS/MET experiment was the first active atmospheric microwave occultation experiment using the existing GPS L1 and L2 frequencies to measure the atmospheric refractive index. One major limitation to this technique is that the presence of water vapor in amounts typically found in the lower troposphere (below 5-7 km) causes an ambiguity between the contributions of dry air and moisture to the...

Temperature, Salinity and Density Measurements in the Coastal Waters of the Rudsar, South Caspian Sea

CTD (conductivity, temperature and depth) data collected in the coastal waters of Rudsar in summer 2008 were analyzed to identify the isothermal layers, thermocline depth and vertical structure of seawater properties. During the survey, probe was released into the seawater column down to 117 m depth. Results showed a vertical variation of temperature between 29°C at the sea surface and less tha...

Density and Temperature Measurements in a Solar Active Region

We present electron density and temperature measurements from an active region observed above the limb with the Solar Ultraviolet Measurements of Emitted Radiation spectrometer on the Solar and Heliospheric Observatory. Density-sensitive line ratios from Si viii and S x indicate densities greater than 10 cm as high 3 as 200 (or 145 Mm) above the limb. At these heights, static, uniformly heated ...
