我想读< a href = " http://navigator.eumetsat.int/discovery/Start/DirectSearch/DetailResult.do?f % 28 r0 % 29 = EO:设计:DAT: METOP: IASIL1C-ALL nofollow noreferrer“rel = >雅西GDS一级c < / >数据(所有光谱样品)EUMETSAT EPS原生格式,记录在< a href = " http://www.eumetsat.int/website/wcm/idc/idcplg?IdcService=GET_FILE&dDocName=PDF_TEN_96167-EPS-GPFS&RevisionSelectionMethod=LatestReleased&Rendition=Web" rel="nofollow noreferrer">Generic Product Format Specification (PDF, 738 KB, 72 pages) and the IASI Level 1 Product Format Specification (PDF, 2.5 MB, 60 pages). EUMETSAT supports a reading routine in IDL.

The IASI Level 1 Product Guide (PDF, 5.8 MB, 110 pages), section 5.1, notes that

The products can be read using standard HDF libraries

but trying to open a test file with

h5py.File('IASI_xxx_1C_M02_20110528114454Z_20110528132653Z_N_O_20110528132912Z.nat', 'r')

results in

OSError: Unable to open file (Unable to find a valid file signature),

and neither the Generic Product Format Specification nor the IASI Product Format Specification mention HDF, which would be odd if the format was HDF-compatible.

看来你已经下载了一个原生格式文件。这不是一个HDF可读的格式。如果你看到你给出的第一个链接,在分配它注意到有几个格式你可以下载:本机,图像(J2KBW、JPEGBW PNGBW, TIFFBW), BUFR或netCDF。 如果你想使用HDF库读取文件,您需要下载netCDF格式化文件。netCDF符合HDF5库。
