High-temporal-resolution water level and storage change data sets for lakes on the Tibetan Plateau during 2000–2017 using multiple altimetric missions and Landsat-derived lake shoreline positions Xingdong Li1, Di Long1, Qi Huang1, Pengfei Han1, Fanyu Zhao1, and Yoshihide Wada2 1State Key Laboratory of Hydroscience and Engineering, Department of Hydraulic Engineering, Tsinghua University, Beijing, China 2International Institute for Applied Systems Analysis (IIASA), 2361 Laxenburg, Austria Correspondence: Di Long ([email protected]) Received: 21 February 2019 – Discussion started: 15 March 2019 Revised: 4 September 2019 – Accepted: 22 September 2019 – Published: 28 October 2019 Abstract. The Tibetan Plateau (TP), known as Asia’s water tower, is quite sensitive to climate change, which is reflected by changes in hydrologic state variables such as lake water storage. Given the extremely limited ground observations on the TP due to the harsh environment and complex terrain, we exploited multiple altimetric mis- sions and Landsat satellite data to create high-temporal-resolution lake water level and storage change time series at weekly to monthly timescales for 52 large lakes (50 lakes larger than 150 km2 and 2 lakes larger than 100 km2) on the TP during 2000–2017. The data sets are available online at https://doi.org/10.1594/PANGAEA.898411 (Li et al., 2019). With Landsat archives and altimetry data, we developed water levels from lake shoreline posi- tions (i.e., Landsat-derived water levels) that cover the study period and serve as an ideal reference for merging multisource lake water levels with systematic biases being removed. -

Cloudsat CALIPSO
www.nasa.gov andSpaceAdministration National Aeronautics & CloudSat CALIPSO Clean air is important to everyone’s health and well-being. Clean air is vital to life on Earth. An average adult breathes more than 3000 gallons of air every day. In some places, the air we breathe is polluted. Human activities such as driving cars and trucks, burning coal and oil, and manufacturing chemicals release gases and small particles known as aerosols into the atmosphere. Natural processes such as for- est fires and wind-blown desert dust also produce large amounts of aerosols, but roughly half of the to- tal aerosols worldwide results from human activities. Aerosol particles are so small they can remain sus- pended in the air for days or weeks. Smaller aerosols can be breathed into the lungs. In high enough con- centrations, pollution aerosols can threaten human health. Aerosols can also impact our environment. Aerosols reflect sunlight back to space, cooling the Earth’s surface and some types of aerosols also absorb sunlight—heating the atmosphere. Because clouds form on aerosol particles, changes in aerosols can change clouds and even precipitation. These effects can change atmospheric circulation patterns, and, over time, even the Earth’s climate. The Air We Breathe The Air We We need better information, on a global scale from satellites, on where aerosols are produced and where they go. Aerosols can be carried through the atmosphere-traveling hundreds or thousands of miles from their sources. We need this satellite infor- mation to improve daily forecasts of air quality and long-term forecasts of climate change. -

Generally speaking, operational satellites have a long lifetime and often several near-identical copies, whereas scientific satellites are unique and have a more limited lifetime, but produce more advanced data. An example of a scientific satellite is the CloudSat, a NASA satellite flying in the so-called "A-Train" formation with other satellites. Examples of operational satellites are the NOAA and MetOp meteorological satellite series. CloudSat carries a 94 GHz nadir viewing radar instrument measuring pro- files of clouds. The NOAA-15 to NOAA-18 and MetOp-A satellites carry radiometers at various frequencies ranging from the infrared (3.76 µm) to around 183 GHz (≈ 1:6 mm). The full range is covered by the High Res- olution Infrared Radiation Sounder (HIRS) and the Advanced Microwave Sounding Units (AMSU-A and AMSU-B). On newer satellites, AMSU-B has been replaced by the Microwave Humidity Sounder (MHS) with nearly the same characteristics. -

GPM Precipitation Estimation and Validation Activities
CGMS-36, NASA-WP-02 Prepared by NASA Agenda Item: WGII/4 Discussed in Working Groups GPM Precipitation Estimation and Validation Activities Precipitation estimation and validation activities of the Global Precipitation Measurement (GPM) mission, a NASA/JAXA joint satellite effort is reported as requested in CGMS-35 Action Item 35.22. An introduction to GPM, a status of GPM estimation and validation activities, and future plans are provided. CGMS-36, NASA-WP-02 1 Introduction The center piece of NASA’s activities on precipitation estimation and validation is its role in the Global Precipitation Measurement (GPM) mission, being developed primarily by NASA and the Japan Aerospace and Exploration Agency (JAXA). GPM marks an evolution from the current effort built around uncoordinated individual satellite missions towards one coordinated, inter-calibrated satellite constellation providing uniform global precipitation products. An important component as a starting point in creating this coordinated precipitation- measuring constellation already exists, in the form of the highly successful U.S.-Japan Tropical Rainfall Measuring Mission (TRMM), in operation since 1997, which continues to provide first-generation tropical precipitation estimates used in both societal applications and scientific research. The GPM mission will serve as the cornerstone for international collaboration on satellite precipitation algorithm research, ground validation, data processing, and product dissemination. To these ends, NASA is working with the international science community to develop a consensus reference standard for cross-calibration of microwave radiometers to produce uniform global precipitation products. NASA and JAXA have devoted substantial resources through TRMM and GPM in data processing and science team support, to include the development of Level 1C prototypes for intercalibration of current radiometers using the TRMM PR and TMI as a reference. -
Cloudsat Overview
CloudSat Overview CloudSat will provide, from space, the first global survey of cloud profiles and cloud physical properties, with seasonal and geographical variations, needed to evaluate the way clouds are parameterized in global models, thereby contributing to improved predictions of weather, climate and the cloud-climate feedback problem. CloudSat will measure the vertical structure of clouds and precipitation from space primarily through 94 GHz radar reflectivity measurements, but also by using a combination of observations from the EOS-PM Constellation of satellites (A-Train). CloudSat will fly in on-orbit formation with the Aqua and CALIPSO satellites, providing a unique, multi-satellite observing system particularly suited for studying the atmospheric processes of the hydrological cycle. 1. Science Objectives • Evaluate the representation of clouds in weather and climate prediction models. CloudSat will provide a global survey of the vertical structure of cloud systems: This vertical structure is fundamentally important for understanding how clouds affect both their local and large-scale atmospheric and radiative environments. • Evaluate the relationship between cloud liquid water and ice content and the radiative properties of clouds. CloudSat will estimate the profiles of cloud liquid water and ice water content. These are the quantities predicted by cloud-process and global-scale models alike and determine practically all important cloud properties, including precipitation and cloud optical properties. CloudSat will provide coincident profile information on the bulk cloud microphysical properties matched to cloud optical properties. Optical properties contrasted against cloud liquid water and ice contents provide a critical test of key parameterizations that enable calculation of flux profiles and radiative heating rates throughout the atmospheric column. -

Abstract: LiDAR and CALIPSO satellites are effective tools for detecting air pollution, and by employing PM2.5 observation data, ground-based LiDAR measurements, CALIPSO satellite data, meteorological data, and back-trajectory analysis, we analyzed the process of pollution (moderate pollution, heavy pollution, excellent weather, and dust transmission weather) in Hefei, China from 24 to 27 January 2019 and analyzed the meteorological conditions and pollutants causing heavy pollution. Observation data from the ground station showed that the concentrations of PM10 and 3 PM2.5 increased significantly on 25 January; the maximum value of PM10 was 175 µg/m , and 3 the maximum value of PM2.5 was 170 µg/m .
