The main aim of this study is to analyse spatial and temporal variation total column ozone as well the trend over Turkey with MERRA-2 Reanalysis for period 1980-2019. First all, compared Brewer Spectrophotometer located in Ankara study. As a result, it found that agrees quite (R2=0.9781) from Spectrophotometer. analysis indicates statistically significant decreasing 1980-1999 period, non-signif...

Short-duration rainfall extremes are expected to intensify with warming at around 7%/K, following the Clausius-Clapeyron (CC) relation, causing concomitant increases in flash floods. Observed hourly show consistent CC-scaling dewpoint temperature across all land regions. Here, we use two global climate reanalysis products (ERA5 and MERRA-2) examine consistency scaling observations, ungauged reg...

Global navigation satellite system (GNSS) radio occultation (RO) receivers onboard the recently-launched COSMIC-2 (C2) constellation provide an unprecedented number of high vertical resolution moisture profiles throughout tropical and subtropical atmosphere. In this study, distribution variability water vapor was investigated using specific humidity retrievals from C2 observations compared to c...

For several years passive microwave observations have been used to retrieve soil moisture from the Earth’s surface. Low frequency observations have the most sensitivity to soil moisture, therefore the current Soil Moisture and Ocean Salinity (SMOS) and future Soil Moisture Active and Passive (SMAP) satellite missions observe the Earth’s surface in the L-band frequency. In the past, several sate...

Regional climate models (RCMs) in general can simulate the characteristics of heavy/extreme precipitation more accurately than general circulation models (GCMs) as a result of more realistic representation of topography and mesoscale processes. An analogue method of statistical downscaling, which identifies the resolved large-scale atmospheric conditions associated with heavy precipitation, is ...

Two three-dimensional reanalysis datasets of atmospheric composition, the Copernicus Atmosphere Monitoring Service (CAMSRA) and Modern-Era Retrospective Analysis for Research Applications, version 2 (MERRA-2), are analyzed years 2003–2018 with respect to dust transport into Arctic. The reanalyses agree on that largest mass Arctic occurs across western Russia during spring early summer, bu...

Fast-growing energy demand of the world makes researchers focus on finding new sources or optimizing already-developed approaches. For an efficient use solar and wind in system, correct design sizing a power system is high importance improving process data obtaining for this purpose leads to higher performance lower cost per unit energy. It essential have most precise possible estimation potent...

The NASA Catchment land surface model (CLSM) is the land model component used for the Modern-Era Retrospective Analysis for Research and Applications (MERRA). Here, the CLSM versions of MERRA and MERRA-Land are evaluated using snow cover fraction (SCF) observations from the Moderate Resolution Imaging Spectroradiometer (MODIS). Moreover, a computationally-efficient empirical scheme is designed ...
