Now she’s trying to correlate her findings with those of the two research teams operating on the other side of the Pacific，where at one point the pollution plume was larger than Japan．The huge size of the cloud showed up clearly in satellite images that gave Price plenty of warning the haze was on 1ts way．“You can see these two blobs coming out of the deserts of Mongolia and growing over Asia，then getting swept out over the ocean and finally setting over North America,” she said．She Intends to continue measuring air samples off the Washington coast and will be looking for air masses with evidence of pollution originating somewhere other than Asia．“We’d like to see if we can get a signature of pollution coming from Europe because computer models suggest that European sources also can be transported across the Pacific，”she said．“However, we expect that sources in Europe will contribute less than Asian sources．”
