Max_Temp looks incorrect

Hi Adam,
For certain stations, the data(TMAX) seems incorrect. When I view the data for a specific year for these particular stations using the web tool, I get different data .

For e.g. for the station, RIVERSIDE FIRE STATION 3, CA US (GHCND:USC00047470), I am getting
TMAX in range of 200, which seems incorrect. I get different results when queried from web
(https://www.ncdc.noaa.gov/cdo-web/datasets/GHCND/stations/GHCND:USC00047470/detail).

#Example
from datetime import date
from pyncei.reader import NCEIReader
import datetime as dt
import csv
import pandas as pd

token = '##############'
ncei = NCEIReader(token,encode_queries=False)
mindate = '1970-01-01' # either yyyy-mm-dd or a datetime object
maxdate = dt.datetime.today().strftime("%Y-%m-%d")
datatypes = ['TMAX']
dataset = 'GHCND'
minyear = int(mindate[:4])
year = date.today().year
val='GHCND:USC00047470'
ncei.get_data(dataset=dataset,
station=val,
datatype=datatypes,
startdate=date(1990, 1, 1),
enddate=date(1990, 12, 31))

There are several other stations for which the data seems incorrect.

Thanks

Hi Adam,
Could you kindly tell what could be the reason for this difference.

Thanks

This has to do with the how the NCEI data endpoint returns data if no units keyword is specified. I’ve added that keyword to the get_data() method. It accepts either ‘standard’ or ‘metric’. I think that should solve your issue, but let me know if not. Thanks! Adam

Hi Adam,
It works now.

Thanks
