我有一个.nc文件，其中纬度和经度在二维数组中。我想提取某些已知点的值。我没有找到找到该已知点的索引的方法。
数据结构如下所示：
OrderedDict([(u'lon', <type 'netCDF4._netCDF4.Variable'>
float32 lon(y, x)
standard_name: longitude
long_name: longitude
units: degrees_east
_CoordinateAxisType: Lon
unlimited dimensions:
current shape = (146, 209)
filling off), (u'lat', <type 'netCDF4._netCDF4.Variable'>
float32 lat(y, x)
standard_name: latitude
long_name: latitude
units: degrees_north
_CoordinateAxisType: Lat
unlimited dimensions:
current shape = (146, 209)
filling off), (u'time', <type 'netCDF4._netCDF4.Variable'>
float64 time(time)
standard_name: time
units: seconds since 1949-12-1 00:00:00
calendar: proleptic_gregorian
axis: T
unlimited dimensions: time
current shape = (55152,)
filling off), (u'TOT_PREC', <type 'netCDF4._netCDF4.Variable'>
float32 TOT_PREC(time, y, x)
standard_name: precipitation_amount
long_name: total precipitation amount
units: kg m-2
coordinates: lat lon
cell_methods: time: sum
unlimited dimensions: time
current shape = (55152, 146, 209)
filling off)])
假设我想将值提取到坐标为的点：lat=27.25，lon=85.75那么如何获取这些坐标的经度和经度索引呢？
首先，读取 .nc 文件和里面的变量
ds1 = NetCDFFile('file.nc')
ds2 = ...
lon = ds.variables['lon'][:]
lat = ds.variables['lat'][:]
然后使用 'for' 循环 {}{}{} lat，lon，data 写入文件 然后你很容易读取数据。 希望这是有道理的。
