    Atmospheric and oceanic stable isotope signatures of a cold-air outbreakin Iceland during YOPP SOP1 and IGP 
    Sodeman, Harald; Touzeau, Alexandra; Weng, Yongbiao; Golid, Heidi; Steen-Larsen, Hans Christian; Barstad, Idar; Lazky, Mika; Lacour, Jean-Lionel; Burkhart, John; Renfrew, Ian; Sveinbjörnsdóttir, Árný (European Geosciences Union, 2019)
    North-Atlantic Cold-air outbreaks are weather events characterised by extensive fluxes of latent heat to theatmosphere. Understanding the water budget of these weather events is important for the weather impact indownstream ...

    Decadal Spatial-Temporal Variations in the Spatial Pattern of Anomalies of Extreme Precipitation Thresholds (Case Study: Northwest Iran) 
    Rousta, Iman; Nasserzadeh, Mohammad; Jalali, Masoud; Haghighi, Esmaeil; Olafsson, Haraldur; Ashrafi, Saeide; Doostkamian, Mehdi; Ghasemi, Ali (MDPI AG, 2017-08-03)
    This study focused on decadalvariations of extreme precipitation thresholds within a 50-year period (1961–2010) for 250 stations of Iran’s northwest. The 99th percentile was used as the threshold of extreme precipitation. In order to analyze threshold ...

    Freshwater exports from Arctic to the Labrador and Greenland shelf andslope. 
    Benetti, Marion; Reverdin, Gilles; Holliday, Penny; Olafsdottir, Solveig; Lherminier, Pascale; Sarthou, Geraldine; De Steu, Laura; Sveinbjörnsdóttir, Árný; Valdes, Sinhue Torres; Tynan, Eithne; Yashayaev, Igor; Olafsson, Jon (European Geosciences Union, 2017)
    We investigate whether one can detect changes in the freshwater contributions to the North Atlantic subpolar gyre(SPG), in light of the observed recent decrease of salinity in the region. We focus on two important conduits offreshwater from the ...

    Gap-Filling of MODIS Time Series Land Surface Temperature (LST) Products Using Singular Spectrum Analysis (SSA) 
    Ghafarian Malamiri, Hamid; Rousta, Iman; Olafsson, Haraldur; Zare, Hadi; Zhang, Hao (MDPI AG, 2018-08-23)
    Land surface temperature (LST) is a basic parameter in energy exchange between the land and the atmosphere, and is frequently used in many sciences such as climatology, hydrology, agriculture, ecology, etc. Time series of satellite LST data have ...

    Investigation of Vorticity during Prevalent Winter Precipitation in Iran 
    Rousta, Iman; Javadizadeh, Farshad; Dargahian, Fatemeh; Olafsson, Haraldur; Shiri-Karimvandi, Amin; Vahedinejad, Sayed Hossein; Doostkamian, Mehdi; Monroy Vargas, Edgar Ricardo; Asadolahi, Anayat (Hindawi Limited, 2018-09-30)
    In this study, precipitation data for 483 synoptic stations, and the U&V component of wind and HGT data for 4 atmospheric levels were respectively obtained from IRIMO and NCEP/NCAR databases (1961–2013). The precipitation threshold of 1 mm and a minimum ...
