EC携机器学习洗牌预报模式
EC 机器学习 洗牌 预报模式
2020/6/8
近日，欧洲中期天气预报中心（ECMWF，简称EC）邀请国际上知名的机器学习研究者，在线上举办机器学习应用于天气预报和气候研究系列讲座，推动员工和学术界在研发中树立应用机器学习技术的意识。这样的举动既是在培育新的交叉学科，又在借助机器学习等新技术探索预报模式系统的发展方向。
Size distributions of dicarboxylic acids, ketoacids, α-dicarbonyls, sugars, WSOC, OC, EC and inorganic ions in atmospheric particles over Northern Japan: implication for long-range transport of Siberian biomass burning and East Asian polluted aerosols
atmospheric particles Northern Japan Siberian biomass burning and East Asian polluted aerosols
2010/8/13
To better understand the size-segregated chemical composition of aged organic aerosols in the western North Pacific rim, day- and night-time aerosol samples were collected in Sapporo, Japan during sum...
Positive sampling artifact of carbonaceous aerosols and its influence on the thermal-optical split of OC/EC
carbonaceous aerosols thermal-optical split OC/EC
2009/10/9
Accurate measurement of carbonaceous aerosols is challenging, due to the sampling artifact and the problems of the split of OC/EC. Two approaches have been used to account for the positive artifact: b...
Fossil and non-fossil sources of organic carbon（OC）and elemental carbon（EC）in Göteborg, Sweden
Fossil and non-fossil sources organic carbon OC elemental carbon EC Gö teborg
2009/3/13
Particulate matter was collected at an urban site in Göteborg (Sweden) in February/March 2005 and in June/July 2006. Additional samples were collected at a rural site for the winter period. Total...
On the isolation of elemental carbon (EC) for micro-molar 14C accelerator mass spectrometry: development of a hybrid reference material for 14C-EC accuracy assurance, and a critical evaluation of the thermal optical kinetic (TOK) EC isolation procedure
elemental carbon EC TOK
2009/2/18
The primary objective of the research reported here has been the development of a hybrid reference material (RM) to serve as a test of accuracy for elemental carbon (EC) isotopic (14C) speciation meas...
Size distribution of EC and OC in the aerosol of Alpine valleys during summer and winter
Size distribution EC OC aerosol of Alpine valleys
2009/1/14
Collections of samples were conducted for the determination of the size distributions of EC and OC during the intensive sampling campaigns of the POVA program, in two Alpine valleys of the French Alps...
A TGA/FT-IR study for measuring OC and EC in aerosol samples
TGA/FT-IR study OC EC aerosol samples
2008/12/30
Carbon analysis consists in the evaluation of the carbonaceous content of the aerosol (TC) but, more importantly, of its distribution between the two components EC (Elemental Carbon) and OC (Organic C...
Seasonal variation of PM10 main constituents in two valleys of the French Alps. I: EC/OC fractions
Seasonal variation valley French Alps. I: EC/OC fractions
2008/12/1
Daily PM10 samples were collected at two urban sites within two valleys in the French Alps (Chamonix and St Jean de Maurienne) during a period of two and a half years. The carbonaceous species EC (ele...
