Sentences with phrase «mean atmospheric measurements»

All that doesn't mean atmospheric measurements from satellites and balloons are worthless, unreliable, or uninformative.

From in situ measurements made over a 20 - month period by the Tunable Laser Spectrometer (TLS) of the Sample Analysis at Mars (SAM) instrument suite on Curiosity at Gale Crater, we report detection of background levels of atmospheric methane of mean value 0.69 ± 0.25 ppbv at the 95 % confidence interval (CI).

Large scale dust storms change the atmospheric opacity and convection; as always when comparing mean temperatures, the altitude at which the measurement is made matters, but to the extent it is sensible to speak of a mean temperature for Mars, the evidence is for significant cooling from the 1970's, when Viking made measurements, compared to current temperatures.

Alaska Arctic Tundra CH4 Flux Study — Impacts of AGW / CC Published 8 - Jan 2018 Estimating regional - scale methane flux and budgets using CARVE aircraft measurements over Alaska Conclusions Analysis of CH4 column enhancements supplemented by simulated atmospheric transport allowed us to estimate the monthly - mean CH4 fluxes from our study domain (50 — 75 N, 130 — 170 W).

Validation of the CO2 inversion product (v16r1): mean bias of the atmospheric component of this product with respect to independent aircraft measurements in the free troposphere.

Measurements of atmospheric isotopes such as C12 / C13 can not prove anything either because CO2 ′ s residence time based on the IPCC's figures in 2007 - AR4 is 3.8 years meaning the C12 / C13 ratio can not change substantially because human CO2 is rapidly absorbed by natural sinks.

For instance the Vostok ice - core data over 415,000 years has an average measurement - spacing of 756 years, meaning that the likelihood of measuring an increase in atmospheric CO2 as the one measured at Mauna Loa over the last 50 years, if one existed in the Vostok ice - core samples, amounts to 6.6 % (i.e. 50/756).

My standard example of this is the atmospheric physicists who blithely assume that the mean global temperature curve is actually a measurement.

The observed annual mean latitudinal gradient of atmospheric CO2 concentration during the last 20 years is relatively large (about 3 to 4 ppm) compared with current measurement accuracy.

With the ever increasing divergence of surface temperatures (NASA GISS) from satellite ones (UAH / RSS), and the subsequent divergence of overheated climate models (IPCC CMIP5) to observed reality, it is worth some background on the atmospheric temperature measurement systems used to measure the temperature of the lower troposphere — the exact place where global warming theory is meant to occur and be measured:

In the article «Global atmospheric particle formation from CERN CLOUD measurements,» sciencemag.org, 49 authors concluded «Atmospheric aerosol nucleation has been studied for over 20 years, but the difficulty of performing laboratory nucleation - rate measurements close to atmospheric conditions means that global model simulations have not been directly based on experimental data.....

The atmospheric level reported is a mean concentration from three weeks of measurements during both summer 2005 and spring 2006 (21).

Matrosov S. Y. and D. D. Turner (March 2018): Retrieving mean temperature of atmospheric liquid water layers using microwave radiometer measurements.

This process, commonly known as the greenhouse effect, has been discovered many years ago and was later confirmed by means of laboratory experiments and atmospheric measurements.
