![]() ![]() Many countries have developed and operated their own short-term air quality forecasting systems (refer to Supplementary Note 1). Because of the human toxicity of high PM 2.5, the South Korean Ministry of Environment (KMoE) has been performing PM 2.5 forecasts since 2014 for the purpose of promptly alerting South Korean citizens of hazy events as well as for preparing national emergency programs for reducing the emissions of air pollutants. High PM 2.5 can lead to high occurrence rates of stroke, ischemic heart diseases (IHD), chronic obstructive pulmonary diseases (COPD), and lung cancer 3, 4. Detrimental effects of PM 2.5 on human health have been well recognized. Particulate matter with aerodynamic diameters smaller than 2.5 μm (PM 2.5) has come to represent a serious societal issue in South Korea and China, because their ambient concentrations frequently exceed criteria concentrations, particularly during winter and spring seasons 1, 2. ![]() This study first presents that the scarcity of information is mainly associated with cloud masking, sun-glint effect, and ill-location of satellite-borne data, and it then demonstrates that an advanced air quality modeling system equipped with synergistically-combined information can achieve substantially improved performances, producing enhancements of approximately 10%, 19%, 29%, and 10% in the predictability of PM 2.5 over South Korea in terms of index of agreement (IOA), correlation coefficient (R), mean biases (MB), and hit rate (HR), respectively, compared to PM 2.5 prediction systems using only LEO satellite-derived observations. Such a synergistic combination of information can effectively overcome the major obstacle of scarcity of information, which frequently occurs in PM 2.5 prediction systems using low Earth orbit (LEO) satellite-borne observations. While specifically focusing on the latter factor, this study attempts to demonstrate how information from classical ground observation networks, a state-of-the-art geostationary (GEO) satellite sensor, and an advanced air quality modeling system can be synergistically combined to improve short-term PM 2.5 predictability over South Korea. The short-term predictability of PM 2.5 (and PM 10) is determined by two main factors: the performance of the air quality model and the precision of the initial states. ![]() Because of the detrimental effects of PM 2.5 on human health, many countries and international organizations have developed and operated regional and global short-term PM 2.5 prediction systems. oddly it was new for me when I heard it which was strange as I heard loads of Bob Marley growing up and loved it.Concentrations of ambient particulate matter (such as PM 2.5 and PM 10) have come to represent a serious environmental problem worldwide, causing many deaths and economic losses. No real story, just listened to it once and was in a trance. In true collaborative style the duo have split their choice of 10 tracks between them, kicking off with some classic reggae and rap from T and moving on to Andy’s selection of punk, reggae and a 1968 protest song. Relly agreed to give us their musical selection for our feature ‘My Life In 10 Songs’ and they tell Joyzine about the music playing when they were growing up, it’s strong emotional effect and how it can wake you up to the possibilities of, not only what what music can do, but ultimately how it can turn you into a musician yourself. Within two songs I had two involuntary reactions: I turned the volume way up and starting head nodding like that manic Churchill dog.”Īt Joyzine we like to get artists to shine a light on their influences and highlight the tracks that blew them away, inspired them and helped shape them into the outstanding musicians they are today. ![]() I’ve often equated going the Joyzine submissions inbox as panning for gold (subjective gold, obviously) and this album shone out like a beacon. I reviewed it for Joyzine at the end of July and said “ it’s a stone-cold instant classic. Relly who recently released their incredible album All Welcome On Planet Ree-Vo. Ree-Vo are Bristol-based musician and music producer Andy Spaceland (AKA Andy Jenks) and rapper T. ![]()
