Title Effects of urban nighttime light on the growth of Cinnamomum camphora Type Journal Article
Year 2019 Publication Ying Yong Sheng Tai Xue Bao Abbreviated Journal
Volume 30 Issue 7 Pages 2284-2290
Keywords Plants
Abstract To understand the effects of urban artificial nighttime light on the growth of evergreen trees, we conducted a field investigation in a typical urban street planted with Cinnamomum camphora (a common evergreen street tree species in eastern China) in the Nanjing City, China. Along the street, trees from two types of growing locations with contrasting distances from the street lamp (just under the lamp vs. between two adjacent lamps) were selected. The growth-related plant functional traits were measured and compared. The results showed that trees grown under the lamp had a mean diameter at beast height (DBH) of 16.8 cm, current-year branch productivity (CBP) of 309.4 g·m-2, current-year leaf productivity (CLP) of 241.5 g·m-2, and leaf relative chlorophyll content (LCC) of 34.6 SPAD. Trees grown between lamps had a mean DBH of 15.5 cm, CBP of 273.4 g·m-2, CLP of 212.8 g·m-2, and LCC of 33.1 SPAD. DBH, CBP, CLP and LCC of the trees under the lamp were significantly higher than those between lamps. There was no significant difference in specific leaf area between trees from the two locations. Our results suggested that urban artificial nighttime light could promote the growth of C. camphora, and alter sunlight-determined characteristics of canopy growth vigor.

为了解常绿乔木对城市夜间灯光的生长响应,以华东地区典型常绿行道树种香樟为对象,研究南京市一条典型道路上近灯处(路灯正下方)和远灯处(两相邻路灯中间位置)生长区位的夜间光照强度差异性对香樟生长性状的影响.结果表明: 近灯处香樟的平均胸径为16.8 cm,当年生小枝总生产力为309.4 g·m-2,当年生叶片生产力为241.5 g·m-2,叶片相对叶绿素含量为34.6 SPAD.远灯处香樟的平均胸径为15.5 cm,当年生小枝总生产力为273.4 g·m-2,当年生叶片生产力为212.8 g·m-2,叶片相对叶绿素含量为33.1 SPAD.近灯处香樟的平均胸径、当年生小枝总生产力、当年生叶片生产力及叶片相对叶绿素含量均显著高于远灯处.两处树木间比叶面积没有显著差异.夜间灯光的补充照明促进了近灯处香樟的生长,并改变了树冠生长对阳光的响应特征.

Title Night-time ground-level ozone trends and variability over the urban sites Type Journal Article
Year 2019 Publication Journal of Sustainability Science and Management Abbreviated Journal
Volume 14 Issue 5 Pages 195-201
Keywords Atmospheric chemistry; air pollution
Abstract This study evaluates the variation of night-time ground-level ozone (O3), nitrogen dioxide (NO2 ) and nitric oxide (NO) from year 2015 to 2016. During this period, the recorded maximum night-time ground-level O3 was 55 ppb at Putrajaya (PT), which have more areas with higher brightness level compared to another urban site, Alor Setar (AS) at 21 ppb. Lower NO concentrations restricted the sinking agents, thus, reducing the depletion rates and resulted in O3 to remain in the atmosphere. The contributor toward night-time ground-level O3 concentration in the urban site was not only NO2 concentration, as light pollution might enhance the O3 formations. The photochemistry rate was commonly accounted to be zero due to the absence of photochemical reactions at night. However, the minimum photochemistry rate in both urban was recorded at the ranged from 1.50-2.70 ppb, indicating that O3 was also titrated at night even though the value is not as high as during the day.

Title Effect of nocturnal lighting on an ant’s ethological and physiological traits Type Journal Article
Year 2019 Publication MOJ Ecology & Environmental Sciences Abbreviated Journal
Volume 4 Issue 5 Pages 211-218
Keywords Animals
Abstract Artificial nocturnal lighting affects the nature, an impact best studied on vertebrates that are directly depending on the presence or absence of light. Here, we examined on an ant species taken as a model the effects of artificial nocturnal lighting on eleven physiological and ethological traits. Ant workers maintained under nocturnal lighting showed a decrease or a change in their level of activity, food consumption, locomotion, orientation ability, audacity, tactile perception, social relationship, learning and memory. This was largely observed during the night but the effects persisted, at a lower extend, during the day

Title A Year in Space for the CUbesat MULtispectral Observing System: CUMULOS Type Conference Article
Year 2019 Publication 33rd Annual AIAA/USU Conference on Small Satellites Abbreviated Journal
Volume SSC19-XI-01 Issue Pages
Keywords Remote Sensing
Abstract CUMULOS is a three-camera system flying as a secondary payload on the Integrated Solar Array and Reflectarray Antenna (ISARA) mission with the goals of researching the use of uncooled commercial infrared cameras for Earth

remote sensing and demonstrating unique nighttime remote sensing capabilities. Three separate cameras comprise the CUMULOS payload: 1) a visible (VIS) Si CMOS camera, 2) a shortwave infrared (SWIR) InGaAs camera, and 3) a longwave infrared (LWIR) vanadium oxide microbolometer. This paper reviews on-orbit operations during the past year, in-space calibration observations and techniques, and Earth remote sensing highlights from the first year of space

operations. CUMULOS operations commenced on 8 June 2018 following the successful completion of the primary ISARA mission. Some of the unique contributions from the CUMULOS payloads include: 1) demonstrating the use of bright stars for on-orbit radiometric calibration of CubeSat payloads, 2) acquisition of science-quality nighttime lights data at 130-m resolution, and 3) operating the first simple Earth observing infrared payloads successfully flown on a CubeSat. Sample remote sensing results include images of: cities at night, ship lights (including fishing vessels), oil industry gas flares, serious wildfires, volcanic activity, and daytime and nighttime clouds. The CUMULOS VIS camera has measured calibrated nightlights imagery of major cities such as Los Angeles, Singapore, Shanghai, Tokyo, Kuwait City, Abu Dhabi, Jeddah, Istanbul, and London at more than 5x the resolution of VIIRS. The utility of these data for measuring light pollution, and mapping urban growth and infrastructure development at higher resolution than

VIIRS is being studied, with an emphasis placed on Los Angeles. The “Carr”, “Camp” and “Woolsey” fires from the 2018 California fire season were imaged with all three cameras and results highlight the excellent wildfire imaging

performance that can be achieved by small sensors. The SWIR camera has exhibited extreme sensitivity to flare and fire hotspots, and was even capable of detecting airglow-illuminated nighttime cloud structures by taking advantage of the strong OH emissions within its 0.9-1.7 micron bandpass. The LWIR microbolometer has proven successful at providing cloud context imagery for our nightlights mapping experiments, can detect very large fires and the brightest flare hotspots, and can also image terrain temperature variation and urban heat islands at 300-m resolution. CUMULOS capabilities show the potential of CubeSats and small sensors to perform several VIIRS-like nighttime mission areas in which wide area coverage can be traded for greater resolution over a smaller field of view. The sensor

has been used in collaboration with VIIRS researchers to explore these mission areas and side-by-side results will be presented illustrating the capabilities as well as the limitations of small aperture LEO CubeSat systems.
