Three different types of rainfall products – ground based (kriging interpolation), satellite derived (TRMM3B42), and atmospheric model outputs (WRF – Weather Research and Forecasting) – are compared for 1 hydrological year in order to retrieve rainfall patterns at timescales ranging from sub-daily to annual over a watershed of approximately 10000km2 in Peru. An ensemble of three different spatial resolutions is considered for the comparison (27, 9 and 3km), as long as well as a range of timescales (annual totals, daily rainfall patterns, diurnal cycle). WRF simulations largely overestimate the annual totals, especially at low spatial resolution, while reproducing correctly the diurnal cycle and locating the spots of heavy rainfall more realistically than either the ground-based KED or the Tropical Rainfall Measuring Mission (TRMM) products. The main weakness of kriged products is the production of annual rainfall maxima over the summit rather than on the slopes, mainly due to a lack of in situ data above 3800ma.¿s.¿l.¿ This study also confirms that one limitation of TRMM is its poor performance over ice-covered areas because ice on the ground behaves in a similar way as rain or ice drops in the atmosphere in terms of scattering the microwave energy. While all three products are able to correctly represent the spatial rainfall patterns at the annual scale, it not surprisingly turns out that none of them meets the challenge of representing both accumulated quantities of precipitation and frequency of occurrence at the short timescales (sub-daily and daily) required for glacio-hydrological studies in this region. It is concluded that new methods should be used to merge various rainfall products so as to make the most of their respective strengths.Artículo en acceso abiertoManifiesta que la estimación de la precipitación en una amplia gama de escalas de interés para climatólogos, meteorólogos e hidrólogos es considerada un desafío en las altas altitudes de las regiones tropicales, donde la variabilidad espacial de la precipitación es importante, mientras que las mediciones in situ siguen siendo escasas en gran parte debido a las limitaciones operativas.

Menciona que este estudio también confirma que una limitación de TRMM es su bajo rendimiento en áreas cubiertas de hielo, concluyendo que se deben utilizar nuevos métodos para fusionar varios productos de lluvia con el fin de aprovechar al máximo sus fortalezas.application/pdfengEGUHydrology and Earth System Sciences, January 2016, Volume 20, Issue 1, pp 125-141https://www.hydrol-earth-syst-sci.net/20/125/2016/info:eu-repo/semantics/openAccesshttps://creativecommons.org/licenses/by-nc-nd/4.0/Autoridad Nacional del AguaRepositorio institucional - ANAreponame:ANA-Institucionalinstname:Autoridad Nacional del Aguainstacron:ANAEstaciones pluviométricasClimatologíaMonitoreo de lagunas y glaciaresSpatio-temporal assessment of WRF, TRMM and in situ precipitation data in a tropical mountain environment (Cordillera Blanca, Peru)info:eu-repo/semantics/articleCuenca SantaTHUMBNAILANA0001766.pdf.jpgANA0001766.pdf.jpgGenerated Thumbnailimage/jpeg15489https://repositorio.ana.gob.pe/bitstream/20.500.12543/3190/3/ANA0001766.pdf.jpg59a43ad08c183d56d6e72620b0e28a09MD53TEXTANA0001766.pdf.txtANA0001766.pdf.txtExtracted texttext/plain77863https://repositorio.ana.gob.pe/bitstream/20.500.12543/3190/2/ANA0001766.pdf.txt87b28c235a107422f8ce045adee8e601MD52ORIGINALANA0001766.pdfANA0001766.pdfArtículo principalapplication/pdf4416081https://repositorio.ana.gob.pe/bitstream/20.500.12543/3190/1/ANA0001766.pdf81ca7a98550a2bafcbb98c37727d5126MD51LICENSElicense.txtlicense.txttext/plain; charset=utf-80https://repositorio.ana.gob.pe/bitstream/20.500.12543/3190/4/license.txtd41d8cd98f00b204e9800998ecf8427eMD5420.500.12543/3190oai:repositorio.ana.gob.pe:20.500.12543/31902020-07-06 13:46:28.416Repositorio Institucional Autoridad Nacional del Aguabiblioteca@ana.gob.pe
