Comparison of AOD Between CALIPSO and MODIS: Significant
Atmos. Meas. Tech. Discuss., 5, C3425–C3429, Atmospheric 2012 Measurement www.atmos-meas-tech-discuss.net/5/C3425/2012/ Techniques © Author(s) 2012. This work is distributed under Discussions the Creative Commons Attribute 3.0 License. Interactive comment on “Comparison of AOD between CALIPSO and MODIS: significant differences over major dust and biomass burning regions” by X. Ma et al. Anonymous Referee #1 Received and published: 24 December 2012 Comments to the Editor: In this paper, author compares the aerosol optical depth (AOD) retrieved by two sen- sors namely, CALIPSO/CALIOP and Terra-Aqua/MODIS, over major dust and biomass burning regions of the world. Author uses level-3 gridded dataset available from both sensors to perform the analysis. They find that though the spatial patterns in AOT appear similar CALIOP tends to retrieve much lower AOD over the Sahara and north- west China; both are source regions of dust outbreaks. On the other hand, CALIOP is found to be higher-than-MODIS in the retrieved AOD over southern African region C3425 where seasonal biomass burning takes place. However, during burning season over South America, CALIOP tends to be lower-than-MODIS which apparently linked to the aerosol load/AOD. Finally, author attributes the discrepancies observed between two sensors to the algorithmic issues such as lidar ratio in CALIOP inversion and aerosol model and surface reflectance in MODIS algorithm. Though author calls for further research to narrow down the exact source of bias, he/she doesn’t show in this paper which sensor is closer to the ground-truth. My main suggestion to author is that he/she should compare both satellite retrievals with AERONET-measured direct AOD values in order to establish the validity of the two products.

I further agree that extensive copying of this thesis is allowable only for scholarly purposes. It is understood, however, that any copying or publication of this thesis for commercial purposes or financial gain is not allowed without my written consent. Ariege Besson, 02 May 2018 Abstract GRACE is a pair of satellites that fly 220 kilometers apart in a near-polar orbit, mapping Earth’s gravity field by accurately measuring changes in distance between the two satellites. With a 15 year continuous data record and improving data processing techniques, measurements from GRACE has contributed to many scientific findings in the fields of hydrology and geology. Several of the applications of GRACE data include mapping groundwater storage changes, ice mass changes, sea level rise, isostatic rebound from glaciers, and crustal deformation. Many applications of GRACE data have profound implications for society; some further our understanding of climate change and its effects on the water cycle, others are furthering our understanding of earthquake mechanisms.

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.

IEEE TRANSACTIONS ON GEOSCIENCE AND REMOTE SENSING, VOL. 41, NO. 2, FEBRUARY 2003 173 Aqua: An Earth-Observing Satellite Mission to Examine Water and Other Climate Variables Claire L. Parkinson Abstract—Aqua is a major satellite mission of the Earth Observing System (EOS), an international program centered at the U.S. National Aeronautics and Space Administration (NASA). The Aqua satellite carries six distinct earth-observing instruments to measure numerous aspects of earth’s atmosphere, land, oceans, biosphere, and cryosphere, with a concentration on water in the earth system. Launched on May 4, 2002, the satellite is in a sun-synchronous orbit at an altitude of 705 km, with a track that takes it north across the equator at 1:30 P.M. and south across the equator at 1:30 A.M. All of its earth-observing instruments are operating, and all have the ability to obtain global measurements within two days. The Aqua data will be archived and available to the research community through four Distributed Active Archive Centers (DAACs). Index Terms—Aqua, Earth Observing System (EOS), remote sensing, satellites, water cycle. I.

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.
