1. Ground validation and bias correction of GPM-IMERG V6 satellite precipitation product over Sweden
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : This study attempts to assess and correct the performance of Integrated Multi-satellite Retrievals for Global Precipitation Measurement (GPM-IMERG) final run daily precipitation product across Sweden. The performance of GPM-IMERG version 6 final run was evaluated against 677 rain gauges in a period from 12 March 2014 to 31 May 2019. READ MORE

2. Evaluation of X-band Weather Radar Data in Urban Hydrology
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : Throughout history it has always been crucial to accurately measure, track, and predict precipitation. This has been done using various methods with varying degrees of precision. As the world evolves and as urban areas expand, it has become more apparent that there is a need for a more efficient way to observe and record precipitation. READ MORE

3. An evaluation of using GPM satellite products to forecast flash floods in mountainous catchments
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : NASA's GPM satellite rainfall products IMERG early run and IMERG late run were evaluated for their applicability in flash flood forecasting. The selected catchment was the upper Han River basin, a mountainous catchment with low precipitation in winter and heavy precipitation during summers located in central China. READ MORE

4. Correction of Inhomogeneous Data in the Precipitation Time Series of Sweden Due to the Wind Shield Introduction
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : The work of this master thesis is based on analyses of monthly precipitation data from 70 stations of the SMHI (Swedish Meteorological and Hydrological Institute) in Sweden, in the period 1860-2014, using the information for the year of introduction of the wind shield at each station. The primary goal is the calculation of correction factors which will be applied on the precipitation data in the period of measurements before the introduction of the wind shield. READ MORE

5. Evaluation of the use of a Dynamic versus a Simple Correction Model to correct for systematic errors in Swedish Precipitation Data
University essay from Stockholms universitet/Institutionen för naturgeografiAbstract : A Dynamic Correction Model (DCM) was implemented to correct daily precipitation data from the network of precipitation gauges hosted by the Swedish Meteorological and Hydrological Institute (SMHI). The goal was to determine whether the DCM could be used to improve estimates of the influence of systematic errors on precipitation observations compared to a previous assessment made on the SMHI dataset using a Simple Correction Model (SCM).
