Abstract. The Korea–United States Air Quality Study (KORUS-AQ) conducted during May–June 2016 offered the first opportunity to evaluate direct-sun observations of formaldehyde (HCHO) total column densities with improved Pandora spectrometer instruments. measurements highlighted in this work were both Seoul megacity area at Olympic Park site (37.5232∘ N, 27.1260∘ E; 26 m a.s.l.) and a nearby rural downwind city Mount Taehwa research forest (37.3123∘ 127.3106∘ 160 a.s.l.). Evaluation these was...
Abstract Earth experienced the strongest geomagnetic storm in 20 years over 10–13 May 2024. The Ap and Dst indices were 273 −291.94 nT on 11 May. Sounding of Atmosphere using Broadband Emission Radiometry (SABER) instrument Thermosphere‐Ionosphere‐Mesosphere Energetics Dynamics satellite observed significant enhancement thermospheric infrared emission at 15, 5.3, 4.3, 1.27 μm. On daily global power radiated by nitric oxide (NO) 5.3 μm was 1.41 TW carbon dioxide (CO 2 ) 15 1.35 TW. These are...
Mixed Reality (MR) technologies provide users with an environment that incorporates virtual objects and metadata into their physical surroundings. This opens up exciting new possibilities for applications in various domains including: education, training, healthcare, Computer Supported Cooperative Work (CSCW). Recognizing the provides contextual clues can improve user task performance influence effective cognitive load complex tasks. However, this facet of MR is still relatively nascent...
Abstract Time series of radiative cooling the upper mesosphere and lower thermosphere (UMLT) by carbon dioxide (CO 2 ) are examined for evidence trends over 20 years. Radiative rates in K day −1 provided SABER instrument converted to time infrared power radiated from three distinct layers between 0.1 hPa 0.0001 (65–105 km). Linear regression against a predictor solar variability provides estimates trend exiting longwave radiation (ELR) these layers. Trends ELR not significantly different...
We analyze periodic features in the F10.7 cm solar radio flux and Ap geomagnetic index to examine solar-terrestrial coupling Earth's atmosphere above 100 km. The is indicated by same observed global infrared power radiated Nitric Oxide (NO) Carbon Dioxide (CO2). data have been measured SABER instrument on NASA TIMED satellite since January 2002. A strong dominant feature for length of cycle (≈11 years) can be all datasets. this periodicity vary from 9.95 years 12.25 different cycles....
Abstract Twenty‐two years (2002–2023) of infrared radiative cooling rate data derived from the SABER instrument on NASA TIMED satellite are presented. Global daily and global annual power (Watts, W) emitted by nitric oxide (NO) carbon dioxide (CO 2 ) illustrate variability geospace environment timescales days to decades. The 11‐year solar cycle (SC) is evident in vertical profiles rates (nW/m 3 ). radiated NO CO larger 2023 than at any time since 2003 2002, respectively. to‐date peak SC 25...
The F10.7 cm solar radio flux is an excellent indicator of variability whereas the Ap index commonly used to examine geomagnetic activity in earth’s upper atmosphere. These datasets have been analyzed this study detect long and short-term periodic features activities. Additionally, daily global power radiated by Nitric Oxide (NO) Carbon Dioxide (CO2) thermosphere also for characteristics, these data are measured SABER instrument (2002 - present) onboard NASA’s TIMED satellite. A strong...
