I am a PhD student working on global scale. I am working at INRA in France.I am new to R
I downloaded a netcdf file cruncep_tair_2010.nc.gz from http://dods.extra.cea.fr/data/p529viov/cruncep/t2m/ in this file, temperature was measured every 6 hours for 2010, I want to convert to daily and then calculate the max ,min ,average daily temperature I will appreciate it very much if you kindly help me. How can I see the data using R, just to look at the table and then manipulate it I am attaching the tem for one location 45 .13 (log,lat) .(I extracted it using GIS but I don't know if I extracted them correctly) As you can see: time is from 1 to 1460, 1 means they the measure tem for the globe at the first 6 hours , 2=after 12 hours .....; and so on 1460 *6 = 8760 hours which equals 1 year first of all I want to convert from kelvin to degree 1 2 3 4 ------ 1 (min,max,averag)day one map(file) for the globe 5 6 7 8 ------ 2 second map(file) for the . ; ; ; 1460 ------- 365 days so in the end will develop 365 file for daily min Tem 365 file for daily max Tem 365 file for average daily Tem Thanks in advance -- View this message in context: http://r.789695.n4.nabble.com/climate-data-Netcdf-tp4474329p4474329.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
