I downloaded E-OBS gridded data from European climate data assessment (grid datasets website and dataset 1 and dataset 2), and I am interested in 0.25 degree grid data of land surface temperature and precipitation for Germany only, but E-OBS grid data is conducted on whole Europe and all measurement in daily level. However, this grid datasets were divided and each chunk has 15 years climate data observation, and I need 30 years data. So I downloaded two big .nc file from this site, but this file is quite big. I want to read those in ArcGIS desktop as raster and intend to pull out Germany. So I did these in ArcGIS:

from Multidimension Tool.tbx -> Make NetCDF Feature Layer, to see its attribute table of those grid data in ArcGis, but I have only coordinate pair while respective daily temperature observations' attribute table is not shown. Here is the screenshot of reading .nc file as raster in ArcGIS:

+-----+-------------+------------+------------+
| FID |  longitude  |  latitude  |     tg     |

|   1 | -14.6250000 | 25.3750000 | 17.3799992 |
|   2 | -14.3750000 | 25.3750000 | 17.3799992 |
|   3 | -14.1250000 | 25.3750000 | 17.3500004 |

Desired output:

I want to make raster grid from this .nc file and want to have attribute table where grid node' coordinate with respective daily temperature observations.

I am not familiar with working .nc files in R, so I want to read those netCDF file in ArcGIS and want to get raster grid first, then crop all grids of Germany where geo-coordinate must come along with respective daily temperature observation.

How can I make this happen in ArcGIS?

How can I convert grid data in .nc file to regular raster grid in ArcGIS?

Can anyone help me how to get this done easily in geospatial software tools?

  • As per the Tour there should be only one question asked per question. I think you should start by deciding which of ArcGIS Desktop and R you wish to ask about in this particular question. – PolyGeo Apr 27 '18 at 20:01
  • Short answer is library(raster); r <- raster("file.nc"); as.data.frame(r, xy = TRUE) - longer answer is see ?raster and ?crop – mdsumner Apr 28 '18 at 11:30
