把这段代码从python转成Fortran： data = pd.read_csv（r'C：\Users\86133\Desktop\一维线性插值\降水量插值数据.txt'，sep='\s+'，skiprows=0）

Fortran中没有pandas这个库，需要使用其他库来读取csv文件。以下是一种可能的Fortran代码：

program read_csv
implicit none
character(len=100) :: file_name
integer :: i, n
real :: data(1000, 2)
character(len=1) :: sep
integer :: skiprows

file_name = 'C:\Users\86133\Desktop\一维线性插值\降水量插值数据.txt'
sep = ' '
skiprows = 0

open(10, file=file_name)
n = 0
do
read(10, *, iostat=i)
if (i /= 0) exit
n = n + 1
read(file_name, '(f10.2, f10.2)', iostat=i) data(n, :)
if (i /= 0) stop 'Error reading data'
end do
close(10)

print *, 'Read', n, 'lines of data:'
do i = 1, n
print *, data(i, :)
end do

end program read_csv
