“…The African Rainfall Climatology version 2.0 (ARC2) is a revision of the first version of the ARC and is consistent with the operational Rainfall Estimation Version 2 (RFE 2.0) (Novella and Thiaw, 2013). The product is a composite of (i) 3-hourly geostationary infrared (IR) data centered over Africa from the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and (ii) quality-controlled 24 h (06:00-06:00 UTC) rainfall accumulation records from the Global Telecommunication System (GTS) gauge database.…”

Abstract. We introduce the Frequent Rainfall Observations on GridS (FROGS) database (Roca et al., 2019). It is composed of gridded daily-precipitation products on a common 1∘×1∘ grid to ease intercomparison and assessment exercises. The database includes satellite, ground-based and reanalysis products. As most of the satellite products rely on rain gauges for calibration, unadjusted versions of satellite products are also provided where available. Each product is provided over its length of record and up to 2017 if available. Quasi-global, quasi-global land-only, ocean-only and tropical-only as well as regional products (over continental Africa and South America) are included. All products are provided on a common netCDF format that is compliant with Climate and Forecast (CF) Convention and Attribute Convention for Dataset Discovery (ACDD) standards. Preliminary investigations of this large ensemble indicate that while many features appear robust across the products, the characterization of precipitation extremes exhibits a large spread calling for careful selection of the products used for scientific applications. All datasets are freely available via an FTP server and identified thanks to the DOI: https://doi.org/10.14768/06337394-73A9-407C-9997-0E380DAC5598.

“…2a and S2), the overall signal of organic aerosol is much stronger in these two sets, such that the absolute concentration of oxalate (MO7: 0.47 µg m −3 ; MO8: 0.42 µg m −3 ) is still greater than in MO12 (0.19 µg m −3 ) and MO14 (0.37 µg m −3 ). However, biomass burning is a welldocumented source of both oxalate and longer-chain dicarboxylic acids (e.g., Falkovich et al, 2005;Nirmalkar et al, 2015;Cheng et al, 2017;Deshmukh et al, 2018;Thepnuan et al, 2019).…”

Long-range aerosol transport and impacts on size-resolved aerosol composition in Metro Manila, Philippines

et al. 2020

This study analyzes long-range transport of aerosol and aerosol chemical characteristics based on instances of high-and low-aerosol-loading events determined via ground-based size-resolved aerosol measurements collected at the Manila Observatory in Metro Manila, Philippines, from July to October 2018. Multiple data sources, including models, remote sensing, and in situ measurements, are used to analyze the impacts of long-range aerosol transport on Metro Manila and the conditions at the local and synoptic scales facilitating this transport. Through the use of case studies, evidence of long-range transport of biomass burning aerosol and continental emissions is identified in Metro Manila. Long-range transport of biomass burning aerosol from the Maritime Continent, bolstered by southwesterly flow and permitted by low rainfall, was identified through model results and the presence of biomass burning tracers (e.g., K, Rb) in the ground-based measurements. The impacts of emissions transported from continental East Asia on the aerosol characteristics in Metro Manila are also identified; for one of the events analyzed, this transport was facilitated by the nearby passage of a typhoon. Changes in the aerosol size distributions, water-soluble chemical composition, and contributions of various organic aerosol species to the total water-soluble organic aerosol were examined for the different cases. The events impacted by biomass burning transport had the overall highest concentration of water-soluble organic acids, while the events impacted by long-range transport from continental East Asia showed high percent contributions from shorter-chain dicarboxylic acids (i.e., oxalate) that are often representative of photochemical and aqueous processing in the atmosphere. The low-aerosolloading event was subject to a larger precipitation accumulation than the high-aerosol events, indicative of wet scavenging as an aerosol sink in the study region. This low-aerosol event was characterized by a larger relative contribution from supermicrometer aerosols and had a higher percent contribution from longer-chain dicarboxylic acids (i.e., maleate) to the water-soluble organic aerosol fraction, indicating the importance of both primary aerosol emissions and local emissions.

“…Global IR-based datasets cover reasonably long time spans, such as the Climate Hazards Center's Infrared Precipitation with Stations (CHIRPS, [119]) and the Climate Prediction Center (CPC) Merged Analysis of Precipitation (CMAP, [120]). Among the merged IR/MW or MW-only products, it's worth noting the Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks (PERSIANN, [121]), the CPC MORPHing technique (CMORPH, [122]), and the Global Satellite Mapping of Precipitation (GSMaP, [123]). Africa has always been an important target of precipitation estimation, given its relatively poor gauge and radar coverage; the same is true for the tropics, given their importance for global precipitation.…”

Satellite Remote Sensing of Precipitation and the Terrestrial Water Cycle in a Changing Climate

2019

The water cycle is the most essential supporting physical mechanism ensuring the existence of life on Earth. Its components encompass the atmosphere, land, and oceans. The cycle is composed of evaporation, evapotranspiration, sublimation, water vapor transport, condensation, precipitation, runoff, infiltration and percolation, groundwater flow, and plant uptake. For a correct closure of the global water cycle, observations are needed of all these processes with a global perspective. In particular, precipitation requires continuous monitoring, as it is the most important component of the cycle, especially under changing climatic conditions. Passive and active sensors on board meteorological and environmental satellites now make reasonably complete data available that allow better measurements of precipitation to be made from space, in order to improve our understanding of the cycle’s acceleration/deceleration under current and projected climate conditions. The article aims to draw an up-to-date picture of the current status of observations of precipitation from space, with an outlook to the near future of the satellite constellation, modeling applications, and water resource management.
