WebPolar stratospheric clouds (PSCs) are the exception. PSCs appear in the lower stratosphere near the poles in winter. They are found at altitudes of 15 to 25 km (9.3 to 15.5 miles) and form only when temperatures at those heights dip below -78° C. WebThe estimate is based on a TOMS measurement of 18.5 Mt about 36 h after the eruption ended, combined with an observed average decrease in SO 2 in the cloud of 1 to 1.5 Mt per day. We note that TOMS measurements may be subject to errors of about 30% (A. Krueger, personal commun., 1993). Web12 jul. 2014 · Why It Matters.

Web22 nov. 2024 · The temperatures measure roughly -32 degrees C at 75 degrees latitude, -38 degrees C at 60 degrees latitude and -48 degrees C at 45 degrees latitude. Closer to the equator, the tropopause continues to cool. At 30 degrees latitude, the temperature falls to -60 degrees C at 15 km altitude before starting to rise. WebNear the equator, the lower edge of the stratosphere is as high as 20 km (66,000 ft; 12 mi), at midlatitudes around 10 km (33,000 ft; 6.2 mi), and at the poles about 7 km (23,000 ft; …

Webment purposes, the global stratospheric temperature record and understanding of temperature changes were found to be not as sound as those related to ozone changes. The WMO (1995) assessment discussed the observational and modeling efforts through 1994, focussing entirely on trends in lower stratospheric temperatures. This … Web18 feb. 2024 · Long-term data records of temperature profiles spanning the upper stratosphere and mesosphere (US/M hereafter) are sparse and intermittent. This region is, however, far more sensitive to climate change than is the lower atmosphere: US/M temperature trends of ~2-3 K/decade have been reported, compared to ~0.2 K/decade …

WebRecently, much scientific debate has focused on the global temperature of the Earth's lower atmosphere as measured by orbiting satellites. And while these data are exceedingly precise, verified by multiple satellite observations, and balloon measurements taken in-situ, they reveal no discernable warming trend in the Earth's lower atmosphere over the last … Web27 sep. 2024 · Here, measurement effects can significantly affect the retrieved dry temperature, resulting in much greater retrieval noise than at lower altitudes. At low temperatures and densities, the refractive index of the atmosphere is also low, and hence the phase delays measured by the COSMIC GPS radio occultation receivers are very …
