Ī probable cause for the error in MATLAB CDFLIB functions comes from the TT2000 datatype that is used for the epoch variable in MAVEN files. With SPDF version of CDF routines you would get the correct output: > mvninfo = spdfcdfinfo('mvn_lpw_l2_lpnt_20180814_v03_r02.cdf')įilename: 'mvn_lpw_l2_lpnt_20180814_v03_r02.cdf'Īnd spdfcdfread returns the data as a MATLAB array > mvndata = spdfcdfread('mvn_lpw_l2_lpnt_20180814_v03_r02.cdf') With MATLAB provided CDFLIB running on MATLAB 2017a (9.2.0) you get > cdfinfo('mvn_lpw_l2_lpnt_20180814_v03_r02.cdf') The version of cdflib that comes with MATLAB does not support some of the features used in MAVEN files. The Installation instructions are fairly straightforward and there is little that can be added to it. This version of the library is provided for free and can be downloaded directly from SPDF.

Use the cdfread function to read all of the data in the CDF file. The next two variables, Longitude and Latitude, each have only one associated record containing int8 data.

To read the data from NASA Space Physics Data Facility (SPDF) you are encouraged to use the CDF handling library from SPDF. The first variable, Time, consists of 24 records containing CDF epoch data.
