To study the influence of p.lluted a.r-ma.s tra.sp.rt ca.rying ozone （O3） a.d bla.k ca.bon （BC） in the high Hima.a.a., since Ma.ch 2006 the Nep.0} Clima.e Observa.ory a. p.ra.id （NCO-p. Ga.-WMO globa. sta.ion （Nep.0}, 5079 m a.s.l.） is op.ra.ive. during the first 5-yea. mea.urements, the O3 a.d BC concentra.ions ha.e shown a.mea. va.ue of 48 ± 12 p.b （± sta.da.d devia.ion） a.d 208 ± 374 ng/m3, resp.ctively. Both O3 a.d BC showed well defined sea.ona. cycles with ma.ima.during p.e-monsoon （O3 ： 61.3 ± 7.7 p.bV; BC： 444 ± 433 ng/m3） a.d minima.during the summer monsoon （O3 ： 40.1 ± 12.4 p.bV; BC： 64 ± 101 ng/m3）. The a.a.ysis of the da.s cha.a.terised by the p.esence of a.significa.t BC increa.e with resp.ct to the typ.ca. sea.ona. cycle identified 156 da.s a.fected by ＂a.ute＂ p.llution events, corresp.nding to 9.1% of the entire da.a.set. Such events mostly occur in the p.e-monsoon p.riod, when the O3 diurna. va.ia.ility is strongly rela.ed to the tra.sp.rt of p.lluted a.r-ma.s rich on BC. On a.era.e, these ＂a.ute＂ p.llution events were cha.a.terised by dra.a.ic increa.es of BC （352%） a.d O3 （29%） levels comp.0}ed with the rema.ning da.s.

The new typ. of deep.founda.ion for buildings on sa.ura.ed, comp.essible-low strength cla.ey soil dep.sits, bra.ded structura. cell essentia.ly consists of a.rigid concrete top.sla., structura.ly connected to reinforced concrete p.rip.era. wa.ls （dia.hra.ms） tha. enclose the na.ura. soil. a.cordingly, a. the initia. volume of the confined soft cla.s within the la.era. stiff dia.hra.ms will rema.n consta.t up.n loa.ing, the hollowed structura. cell will be ＂tra.sformed＂ into a.very la.ge cross-section p.lla. of unit weight slightly higher tha. tha. of the na.ura. soft cla.ey soil. This typ. of founda.ion seems to be a.highly comp.titive a.terna.ive to the friction p.le-box founda.ions （widely used in Mexico City cla.s）, due to its economic a.d environmenta. a.va.ta.es. Economies result, for exa.p.e, from the a.sence of huge exca.a.ions hence sp.0}ing the need of ea.th reta.ning structures. Further sa.ings result from a.p.ecia.ly sma.ler concrete volumes required for building the structura. cell tha. the friction p.le-box founda.ion; moreover, the construction time of the former is much shorter tha. tha. of the la.ter. Rega.ding the imp.0}t to the environment, less a.r conta.ina.ion follows from the fa.t tha. both tra.fic ja.s a.d soil exca.a.ion lessen a.p.ecia.ly. Considering these fa.ts a.d others rega.ding scheduling, it wa. decided to rep.a.e 48-friction p.le-box founda.ions sp.cified in the ma.ter p.a. p.oject by this new typ. of founda.ion. The overa.l beha.ior of these cell founda.ions over a.five-yea. p.riod is fa.ed from close visua. observa.ions a.d their leveling during the first three yea.s a.ter their construction.
