What Can We Know About Recent Past Precipitation Over Africa? Daily Characteristics of African Precipitation From a Large Ensemble of Observational Products for Model Evaluation

نویسندگان

چکیده

We assess the daily characteristics of recent past precipitation over Africa by means a large ensemble observational products, including reanalysis, gauge-based, and satellite-based products. The spatial distribution seasonal mean varies considerably amongst products especially areas where gauge networks are sparse. Large uncertainties in annual cycle visible particular Ethiopian Highlands, eastern Sahel, coasts Gulf Guinea, Horn Africa. Interannual variability shows differences reanalysis data sets whereas satellite gauge-based usually show more consistent results.

African aerosol and large-scale precipitation variability over West Africa

We investigated the large-scale connection between African aerosol and precipitation in the West African Monsoon (WAM) region using 8-year (2000–2007) monthly and daily Moderate Resolution Imaging Spectroradiometer (MODIS) aerosol products (aerosol optical depth, fine mode fraction) and Tropical Rainfall Measuring Mission (TRMM) precipitation and rain type. These high-quality data further confi...

Hydrological Assessment of Daily Satellite Precipitation Products over a Basin in Iran

In order to measure precipitation as the main variable for estimating the runoff and designing hydraulic structures, the satellite algorithm products that have the proper spatial and temporal coverage, can be used. In this study, at first, the daily streamflow simulation of Sarough-Cahy River from the Zarinehroud basin was conducted through the artificial neural network (ANN) and ground data of...

Molecular approaches to diagnosis of invasive aspergillosis what we know and what we do not know.

Invasive aspergillosis (IA) are a major complication in immunocompromized patients where can be serious and rapidly fatal. Early diagnosis and early appropriate antifungal treatment is important in reducing mortality and morbidity. But despite many efforts to develop detection methods, the diagnosis of IA still remains challenging and current conventional methods are limited for adequate diagno...

Recent observed and simulated changes in precipitation over Africa

Multiple observational data sets and atmosphere-only simulations from the Coupled Model Intercomparison Project Phase 5 are analyzed to characterize recent rainfall variability and trends over Africa focusing on 1983–2010. Data sets exhibiting spurious variability, linked in part to a reduction in rain gauge density, were identified. The remaining observations display coherent increases in annu...

P-138: What Should We Know about Ethical Problem in ART? A Study of Systematic Review

Background: Advances in medical technology have had major impacts on human reproduction. The development of effective contraceptive methods has reduced unwanted fertility, and the development of a variety of drugs and procedures has, for the first time, permitted women with fertility problems to reasonably expect that they can fulfill their desires to have children. So, The aim of this review a...
