Improving Overland Precipitation Retrieval with Brightness Temperature Temporal Variation

Separation of Convective and Stratiform Precipitation Using Microwave Brightness Temperature

This paper presents a new scheme that classifies convective and stratiform (C/S) precipitation areas over oceans using microwave brightness temperature. In this scheme, data are first screened to eliminate nonraining pixels. For raining pixels, C/S indices are computed from brightness temperatures and their variability for emission (19 and 37 GHz) and scattering (85 GHz). Since lower-resolution...

Improving SMOS Salinity Retrieval: Brightness Temperature Calibration and Forward Model Adjustment

The Soil Moisture and Ocean Salinity mission (SMOS) from the European Space Agency, launched in November 2009, has initiated the era of satellite-based salinity observations. The Microwave Interferometric Radiometer with Aperture Synthesis (MIRAS) instrument provides information on the correlation between the measurements done by its set of 72 antennas. However, because of the instrument comple...

Spatio-temporal trend and change detection of temperature and precipitation of Kashafroud basin

 The study of meteorological characteristics and its variability is important in assessing the climate change impacts for water resources management. Trend analysis of hydrological and meteorological time series is a method for determining the change in climate variables that is performed with different parametric and non-parametric methods. In this research, the annual, seasonal and monthly tr...

Spatio-temporal Analysis of Precipitation and Temperature Distribution over Turkey

In this study, mean annual precipitation and temperature values observed at 225 meteorological observations over Turkey are used to disclose spatial distribution of mean annual precipitation and temperature values. Data components were obtained from the Turkish State Meteorological Service for 34 years period (1970-2003). The basic objectives of the study are: to infer the nature of spatial var...
