Abstract. The region of southern Africa (SAF) is among the most exposed climate change hotspots and projected to experience severe impacts across multiple economical societal sectors. For this reason, producing reliable projections expected key for local communities. In work we use an ensemble 19 regional model (RCM) simulations performed in context Coordinated Regional Climate Downscaling Experiment (CORDEX) – a set 10 global models (GCMs) participating Coupled Model Intercomparison Project...
In this paper we present an operational system for drought monitoring and early warning over South Africa-Lesotho. The indicators used the alert issuance are based on meteorological, agricultural hydrological indices, assembled by satellite reanalysis raw data, to cover all aspects of drought. service is operationally updated every 10 days has a spatial resolution Km. A severe period Africa covering time 2017–2020 was test performance system. Our analysis indicated that useful, providing...
Abstract. The region of southern Africa (SAF) is highly vulnerable to the impacts climate change and projected experience severe precipitation shortages in coming decades. Ensuring that our modeling tools are fit for purpose assessing these changes critical. In this work we compare a range satellite products along with gauge-based datasets. Additionally, investigate behavior regional simulations from Coordinated Regional Climate Downscaling Experiment (CORDEX) – domain, Coupled Model...
This study aims to provide insight regarding the future evolution of a series important agroclimatic indicators for specific farming area viticulture in Stimagka, Greece. The calculated cover various aspects climate and its impact on agriculture can be categorized into four broad categories: temperature-, precipitation-, drought-, animal comfort-related indicators. An ensemble state-of-the-art regional model simulations with spatial resolution 12 km are used calculate period 1986–2055. For...
Abstract Earth observation (EO) data are increasingly being used to monitor vegetation and detect plant growth anomalies due water stress, drought, or pests, as well availability, weather conditions, disaster risks, land use/land cover changes evaluate soil degradation. Satellite provided regularly by worldwide organizations, covering a wide variety of spatial, temporal spectral characteristics. In addition, weather, climate crop models provide early estimates the expected climatic patterns...
Erythropotamos is a tributary of river Evros and during the last decade its drainage basin flooded many times, causing extensive damage on properties. In order to assess flood susceptibility in aforementioned study area, inundated areas floods that occurred 2010, 2017 2018 were initially delineated with aid SAR (Synthetic Aperture Radar) imagery by applying an established delineation methodology. Subsequently, mapping was conducted for area Analytical Hierarchy Process (AHP). Topographical,...
Numerous orchid species around the world have already been affected by ongoing climate change, displaying phenological alterations and considerable changes to their distributions. The fly (Ophrys insectifera L.) is a well-known distinctive Ophrys in Europe, with broad distribution across continent. This study explores effects of change on range O. insectifera, using models (SDMs) framework that encompasses different climatic scenarios for near- long-term future. species' environmentally...

Smallholder farmers produce about 70% of Africa's food supply. These are vulnerable to a number risks, mainly climate related, which have tremendous impact on security and thus poverty. Information crop yields, vegetation conditions weather, among others, essential policy makers enhance security. Earth observation data, analytics modeling from various sources, at variety spatial temporal scales could be used support decision making in the field This paper describes crops, water drought...
This study investigates the impact of data assimilation to weather forecasts produced within project "MOSQUITO VISION", concerning development a digital application for mosquito nuisance prediction. The in situ meteorological used are retrieved from Region Central Macedonia (RCM) climate hub, currently including 49 stations compliant with WMO requirements. Here, we assess numerical system's performance by ingesting available observations over RCM through two different techniques using...

<p>According to the National Public Health Organization in Greece, cases of West Nile Virus (WNV) infection humans and animals have been recorded various areas over Greece during years 2010-2014 2017-2019 (https://eody.gov.gr). In this work we present a climate service which supports an Early Warning System (EWS) for mosquito-borne WNV disease, operated first time Region Central Macedonia Greece. The EWS is based on platform fed by time-dependent data (climate information...
<p>One of the main features controlling precipitation over southern Africa during wet season is Angola Low (AL) pressure system that appears as a heat low October and November tropical climatological mean December, January February. The literature provides evidence biases in Coupled Model Intercomparison Project Phase 5 ensemble (CMIP5) are associated with strongly simulated AL. In current work, we examine degree to which this observation holds for CORDEX-Africa (Coordinated...
