Individual orbital scans were converted into time-series and re-projected onto a regular UTM grid (5 km) in R (statistical software), which allowed averaging over time to obtain mean monthly and annual climatological rainfall fields (regular raster grids) from the TPR (in R). Monthly or daily rain gauge time-series for the period 1981-2010 were obtained from IDEAM (Colombia), INAMHI (Ecuador), SENAMHI (Peru), SENAMHI (Bolivia) and NOAA (USA) and mean monthly and annual climatological values were determined for every gauge using a bespoke R script. Gauging station coordinates are re-projected into UTM (in R). Satellite-gauge merging as described in the supporting information was conducted using bespoke R scripts. Following generation of the final merged climatological precipitation fields (regular raster grids) these are converted from R to GeoTIFF (.tif).","metadataDate":"2026-05-11T18:27:37","notGEMINI":true,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/sd/74a588cc-723c-4a35-ac0c-223f5b92ee36.zip","name":"Supporting documentation","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/data/74a588cc-723c-4a35-ac0c-223f5b92ee36","name":"Download the data","description":"Download a copy of this data","function":"download","type":"OTHER"}],"pointsOfContact":[{"familyName":"Manz","givenName":"Bastian","organisationName":"Imperial College London","organisationIdentifier":"https://ror.org/041kmwe10","role":"pointOfContact","email":"bastian.manz10@imperial.ac.uk","address":{"deliveryPoint":"Department of Civil and Environmental Engineering","city":"London ","postalCode":"SW7 2AZ"},"fullName":"Manz, B.","pointOfContact":"Imperial College London"}],"publicationDate":"2016-01-14T00:00:00.000Z","publishers":[{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/74a588cc-723c-4a35-ac0c-223f5b92ee36"},{"code":"10.5285/74a588cc-723c-4a35-ac0c-223f5b92ee36","codeSpace":"doi"}],"resourceMaintenance":[{"frequencyOfUpdate":"notPlanned"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"familyName":"Manz","givenName":"Bastian","organisationName":"Imperial College London","organisationIdentifier":"https://ror.org/041kmwe10","role":"pointOfContact","email":"bastian.manz10@imperial.ac.uk","address":{"deliveryPoint":"Department of Civil and Environmental Engineering","city":"London ","postalCode":"SW7 2AZ"},"fullName":"Manz, B.","pointOfContact":"Imperial College London"},{"familyName":"Manz","givenName":"B.","organisationName":"Imperial College London","organisationIdentifier":"https://ror.org/041kmwe10","role":"author","email":"bastian.manz10@imperial.ac.uk","fullName":"Manz, B."},{"familyName":"Buytaert","givenName":"W.","organisationName":"Imperial College London","organisationIdentifier":"https://ror.org/041kmwe10","role":"author","email":"w.buytaert@imperial.ac.uk","fullName":"Buytaert, W."},{"familyName":"Zulkafli","givenName":"Z.","organisationName":"Imperial College, Universiti Putra Malaysia","role":"author","email":"z.zulkafli10@imperial.ac.uk","fullName":"Zulkafli, Z."},{"familyName":"Lavado","givenName":"W.","organisationName":"Servicio Nacional de Meteorología e Hidrología del Perú (SENAMHI)","organisationIdentifier":"https://ror.org/05h7xpn20","role":"author","email":"Waldo.lavado@gmail.com","address":{"country":"Peru"},"fullName":"Lavado, W."},{"familyName":"Willems","givenName":"B.","organisationName":"Universidad Nacional Mayor de San Marcos","organisationIdentifier":"https://ror.org/006vs7897","role":"author","email":"bwillems@cca.org.pe","fullName":"Willems, B."},{"familyName":"Robles","givenName":"L.A.","organisationName":"Universidad Nacional Mayor de San Marcos","organisationIdentifier":"https://ror.org/006vs7897","role":"author","email":"albert.physik@gmail.com","fullName":"Robles, L.A."},{"familyName":"Rodríguez Sánchez","givenName":"J.-P.","organisationName":"Universidad de los Andes","organisationIdentifier":"https://ror.org/04pqpvr75","role":"author","email":"pabl-rod@uniandes.edu.co","address":{"country":"Colombia"},"fullName":"Rodríguez Sánchez, J.-."},{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"custodian","email":"info@eidc.ac.uk"}],"spatialReferenceSystems":[{"code":"http://www.opengis.net/def/crs/EPSG/0/4326","title":"WGS 84"}],"spatialRepresentationTypes":["grid"],"spatialResolutions":[{"distance":"1000","uom":"m"}],"temporalExtents":[{"begin":"1981-01-01","end":"2014-12-31"}],"title":"High-resolution satellite-gauge merged precipitation climatologies of the tropical Andes","topicCategories":[{"value":"climatologyMeteorologyAtmosphere","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/climatologyMeteorologyAtmosphere"}],"type":"dataset","uri":"https://catalogue.ceh.ac.uk/id/74a588cc-723c-4a35-ac0c-223f5b92ee36","useConstraints":[{"value":"This resource is made available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"},{"value":"© NERC/ Bastian Manz","code":"copyright"}]}
