Programming / Writing two dimensional netCDF file in python-Reg
« on: February 08, 2018, 12:45:42 AM »
Dear all

I tried to write a two dimensional nc file in python. I could able to generate the file but that spatial extent and resolution is not in proper. so it is not showing properly in ArcGIS.

Here is the code
Code: [Select]
from netCDF4 import *
from numpy import *
from openpyxl import *
import time

#Load the data sheet
wb = load_workbook('D:\\R_Workspace\\UB_Try.xlsx')
ws = wb['UB_details']

#To get the prec variable
ppt = []
for i in range(2,1696):

ppt_arr = asarray(ppt)

#Writing nc file
nc_file = Dataset('D:\\R_Workspace\\','w',format='NETCDF4')

nc_file.description = 'Example dataset'
nc_file.history = 'Created on ' +time.ctime(time.time())

#Defining dimensions
lon = nc_file.createDimension('lon',57)
lat = nc_file.createDimension('lat',52)

#Creating variables
latitude = nc_file.createVariable('Latitude',float32,('lat',))
latitude.units = 'Degree_North'
longitude = nc_file.createVariable('Longitude',float32,('lon',))
longitude.units = 'Degree_East'

prec = nc_file.createVariable('prec',float32,('lon','lat'),fill_value = -9999.0)
prec.units = 'mm'

#Writing data to variables
lats = arange(16.875,19.425,0.05)
lat_reverse = lats[::-1]
lons = arange(73.325,76.175,0.05)
latitude[:] = lat_reverse
longitude[:] = lons
temp = zeros(52 * 57, dtype=float32)
temp[:ppt_arr.size] = ppt_arr
prec[:] = temp

created nc file is attached
any suggestions pls.. Thank you..:)

Abstract: To promote the advancement of novel observation techniques that may lead to new sources of
information to help better understand the hydrological cycle, the International Association of
Hydrological Sciences (IAHS) established the Measurements and Observations in the XXI century
(MOXXI) Working Group in July 2013. The group comprises a growing community of techenthusiastic
hydrologists that design and develop their own sensing systems, adopt a multidisciplinary
perspective in tackling complex observations, often use low-cost equipment intended
for other applications to build innovative sensors, or perform opportunistic measurements. This
paper states the objectives of the group and reviews major advancements carried out by
MOXXI members toward the advancement of hydrological sciences. Challenges and
opportunities are outlined to provide strategic guidance for advancement of measurement, and
thus discovery.
