GAW Report, 239. Calibration Methods of GC-μECD for Atmospheric SF6 Measurements
SF6 is a substance which originates only from anthropogenic sources used primarily in the electricity and electronics supply industries, e.g. the semiconductor industry, where it is used as an electronic insulator due to its inertness. SF6 is a trace gas that exists in small quantities at the level of ppt (parts-per-trillion, 1/1012) in the atmosphere, but its global warming potential is 23,500 times greater than that of CO2 when compared over a 100-year period[1]. In particular, SF6 has an atmospheric lifetime of 3,200 years upon emission, and will eventually exacerbate the man-made greenhous ...English
GAW Report, 235. Vegetation Fire and Smoke Pollution Warning and Advisory System (VFSP-WAS): Concept Note and Expert Recommendations
World Meteorological Organization (WMO) ; IBBI ; The Global Fire Monitoring Center (GFMC) - WMO, 2018This concept note contains the expert recommendations resulting from discussions at the international workshop on Forecasting Emissions from Vegetation Fires and their Impacts on Human Health and Security in South-East Asia, which was hosted by the Indonesian Agency for Meteorology, Climatology and Geophysics (BMKG), Jakarta, from 29 August to 1 September 2016. The workshop was organized by the World Meteorological Organization (WMO) and the Interdisciplinary Biomass Burning Initiative (IBBI) in collaboration with the United Nations Office for Disaster Reduction/International Wildfire Prepared ...EnglishAdvances in Space-Based Nighttime Visible Observation, 2nd Edition
This updated one-hour lesson explores the types of atmospheric and surface features that can be observed at night. It describes recent technical improvements in nighttime visible imaging with the VIIRS Day/Night Band on board the Suomi NPP and JPSS satellites, and the lunar phases and other conditions necessary for effective nighttime visible imaging. This lays the foundation for the rest of the lesson, which explores operational uses of nighttime visible observations. These include the detection and monitoring of city lights, tropical cyclones, fog and stratus, polar nights, auroras, fires an ...English

This lesson introduces you to three of the four near-infrared imager bands (at 1.37, 1.6, and 2.2 micrometers) on the GOES R-U ABI (Advanced Baseline Imager), focusing on their spectral characteristics and how they affect what each band observes. For information on the 0.86 micrometer near-IR "veggie" band which is not included here, refer to the Visible and Near-IR Bands lesson. This lesson is a part of the NWS Satellite Foundation GOES-R Course.EnglishSatFC-G: IR Bands, Excluding Water Vapor
This lesson introduces seven of the ten infrared imager bands on the GOES R-U ABI (Advanced Baseline Imager). It examines the spectral characteristics of each band to facilitate a better understanding of band selection and what each band observes, and to shed light on some of the many potential applications. This lesson is a part of the NWS Satellite Foundation GOES-R Course.EnglishSatFC-G: Visible and Near-IR Bands
This lesson introduces you to the two visible and one of the near-infrared imager bands on the GOES R-U ABI (Advanced Baseline Imager), focusing on their spectral characteristics and how they affect what each band observes. Also included is a brief discussion of the customization of visible enhancements as an important consideration for improving the depiction of various features of interest. This lesson is a part of the NWS Satellite Foundation GOES-R Course.English

Aerosols are small, micrometer-sized particles, whose optical effects coupled with their impact on cloud properties is a source of large uncertainty in climate models. Aerosols when inhaled are believed to have significant and detrimental effects on human health. Their presence also affects photosynthesis and agricultural production. Aerosol measurements are urgently required for the complete understanding and modeling their role in the climate system. This study builds on the analysis of Aerosol Optical depth (AOD) using Light Detection and Ranging (LIDAR) and sun photometer measurements then ...English
