[ferret_users] Re: handling data

[golla nageswararao <ezeenag4u@xxxxxxxxx>]

Hi all,

I could solve this problem to some extent by doing gaussian interpolation technique

I used scat2gridgauss_xy function to map the data on profile number and depths.

But now the problem is data size.

I going to get dimension size of 202670x293.

I tried to split the data also, it is giving the following error.
**ERROR in efcn_compute() allocating 475058480 bytes of memory
    work array 3:  X=1:202670, Y=1:293, Z=1:1, T=1:1, E=1:1, F=1:1
 **ERROR: error in external function

The only way to decrease the data size is to extract the data for Indian Ocean domain (original is world oceans)

Can anybody suggest me how to extract for my domain interest (data set is also having longitude and latitude as variables), and compress the data into the reasonable size.

Thanks in advance

Hi all,

I am having a dataset with variables depth, latitude, longitude, temp, salt in only one dimension (i.e., i=1:2600000). Actually the data consists of profiles at different locations.

i=1 z=0 temp1 salt1 lat1 lon1
i=2 z=20 temp1 salt1 lat1 lon1
i=3 z=50 temp1 salt1 lat1 lon1
i=4 z=100 temp1 salt1 lat1 lon1
i=5 z=250 temp1 salt1 lat1 lon1

i=6 z=0 temp2 salt2 lat2 lon2

i=7 z=15 temp2 salt2 lat2 lon2
i=8 z=25 temp2 salt2 lat2 lon2
i=9 z=45 temp2 salt2 lat2 lon2
i=10 z=65 temp2 salt2 lat2 lon2
.

How to handle this type of data? I want to extract profiles in Indian Ocean. I tried to do with "if" command. But the program is coming out of ferret after i=53. I dont know whats the problem. Can anybody help me in this regard.

Thanks in advance.
