Import weather station

[nrfsilva]

Hi Guilhermo,

I am trying to import my weather station, but it is showing the error:

Error in data.frame(date = unique(WSdata$date), radiation_sum = tapply(WSdata$radiation, : arguments imply differing number of rows: 1, 0 In addition: Warning message: In read.WSdata(CSVFILE, date.format = "%d/%m/%Y", lat = -35.42222, : As tz = "", assuming the weather station time zone is America/Sao_Paulo

Do you know, what is going on? I imported your apple.csv, and works but mine file not.

Thank you,

[midraed]

Please check date.format, datetime.format, time.format parameters. They should be correct for your csv. Also check columns parameter. And the "warning" is because you not specifying the time zone with the tz parameter. If the weather station is located in the same timezone than you, should work ok.

Best,

GF

Thank you Guilhermo,

I ordered everything, but it is not working yet.

Follow my code:

library(water) csvfile <- "C:/Users/ZZZZ/ZZZZZ/ZZZZZ/PAPERS/WeatherStation2.csv" WeatherStation <- read.WSdata(WSdata = csvfile, date.format = "%d/%m/%Y", time.format = "%H:%M", lat= -9.324425, long= -40.559563, elev=322, height= 2, columns=c("date" = 1, "time" = 2, "radiation" = 3, "wind" = 4, "RH" = 5, "temp" = 6, "rain" = 7), cf = c(1,1,1), tz = "")

I am not using MTL, because I am using MODIS images.

My WS:

WeatherStation2.zip

Best regards and thank you,

Nildson

Can you show me the first 5 lines of your csv? An image is enough.

BR,

Hello, we are new to water package and trying our own data. Also encountered problems importing our own weather station data.

I get the following error with my code:

WeatherStation <- read.WSdata(WSdata = csvfile, date.format = "%d/%m/%Y", lat=18.094, long= -89.462, elev=279, height=2,tz="GTM-6", columns=c("date" = 1, "time" = 2, "radiation" = 3, "wind" = 4, "RH" = 5, "temp" = 6, "rain" = 7), MTL = MTLfile) Error in Ops.data.frame(WS.after, WS.prev) : ‘-’ only defined for equally-sized data frames In addition: There were 14 warnings (use warnings() to see them)

warnings() Warning messages: 1: In strptime(datetime, format = paste(date.format, time.format), ... : unknown timezone 'GTM-6' 2: In as.POSIXct.POSIXlt(x) : unknown timezone 'GTM-6' 3: In as.POSIXlt.POSIXct(x, tz = tz) : unknown timezone 'GTM-6' 4: In as.POSIXlt.POSIXct(WSdata$datetime) : unknown timezone 'GTM-6' 5: In as.POSIXct.POSIXlt(from) : unknown timezone 'GTM-6' 6: In as.POSIXct.POSIXlt(to) : unknown timezone 'GTM-6' 7: In as.POSIXct.POSIXlt(from) : unknown timezone 'GTM-6' 8: In as.POSIXct.POSIXlt(to) : unknown timezone 'GTM-6' 9: In as.POSIXct.POSIXlt(e1) : unknown timezone 'GTM-6' 10: In check_tzones(e1, e2) : 'tzone' attributes are inconsistent 11: In as.POSIXct.POSIXlt(e2) : unknown timezone 'GTM-6' 12: In as.POSIXct.POSIXlt(e1) : unknown timezone 'GTM-6' 13: In check_tzones(e1, e2) : 'tzone' attributes are inconsistent 14: In as.POSIXct.POSIXlt(e2) : unknown timezone 'GTM-6'

Any ideas? Also, how do I define a different time zone than the one of the computer?

I think I have correctly captured the data formats...

Thank you in advance,

Susana.

[midraed]

To define a gmt zone only use "-6". And if you want to use gmt+6, it has to be "-6". Check strptime()

Ok thanks, but I still get this error:

Error in Ops.data.frame(WS.after, WS.prev) : ‘-’ only defined for equally-sized data frames

what to do about it?

[masaba79]

RESOLVED! The error was due to using "-6". It was resolved by loading library(lubridate), and using tz="America/Merida". Also, we had a wrong date in the weatherstation file...not sure if it had anything to do with the error, but also found out that to be wrong.

Thanks!!

Hello,

I am having an issue reading in the Wx station data. I know that a previous comment already addressed this error message, but I do not know what else to do. Here it is:

Error in data.frame(date = unique(WSdata$date), radiation_sum = tapply(WSdata$radiation, : arguments imply differing number of rows: 1, 0

My format for date is %d/%m%Y, and the actual date is 6/28/2017. The excel doc. is in csv format. Should date and time be in a different class besides 'factor'?

Thank you.

[midraed]

Your date format looks more like %m/%d/%Y, and you have an empty column in the middle

Okay I see now... Thank you. Somewhat new to R Studio.

Hi,

Please I am new to water package. I'm trying to import my weather station, but it is showing error. Below is my code and the error:

WeatherStation <- read.WSdata(WSdata =csvfile, date.format= "%d/%m/%Y", time.format= "%H:%M", lat=42.04306, long=-82.67389, elev=200, height=2.2, columns=c("date" = 1, "time" = 2, "radiation" = 3, "wind" = 4, "RH" = 5, "temp" = 6, "rain" = 7), MTL = MTLfile) Error in data.frame(date = unique(WSdata$date), radiation_sum = tapply(WSdata$radiation, : arguments imply differing number of rows: 1, 0 In addition: Warning message: In read.WSdata(WSdata = csvfile, date.format = "%d/%m/%Y", time.format = "%H:%M", : As tz = "", assuming the weather station time zone is America/New_York

Note: I have read the comments above and I have checked to ensure that my columns are correct and in order. Please what could possibly cause this and what's the possible solution?

Thanks kindly for helping,

Onyeka

[csryan1]

Onyeka,

I got the same error and this worked for me: I read the weather station data within the read.WSdata function. So for me it was a read.csv function within the read.WSdata function. I also let the function find the MTL file in the working directory instead of reading it in beforehand. This may not solve your own issue, but it worked for me.

Hope that helps.

Hi Trying to calculate the actual evapotranspiration using water pack. I've uploaded L8 images, but I'm constantly getting an error while loading the WeatherStation file. I think my csv file is correct because I checked it too. Below is the error message I received from the code and post. I would also appreciate it if you can help drop down the screenshot of my csv file csvfile <- "C: /Users/HP/Desktop/water/INTA_1.csv" MTLfile <- "C: /Users/HP/Desktop/water/LC08_L1TP_175034_20150122_20170413_01_T1_MTL.txt" WeatherStation <- read.WSdata (WSdata = csvfile,                               datetime.format = "% Y /% d /% m% H:% M",                               columns = c ("date" = 1, "radiation" = 5,                                         "wind" = 6, "RH" = 3, "temp" = 2, "rain" = 4),                               lat = 37.0005, long = 35.4183, elev = 65, height = 2,                               MTL = MTLfile)

Error in data.frame (date = unique (WSdata $ date), radiation_sum = tapply (WSdata $ radiation,: arguments imply differing number of rows: 1, 0

[zaib19]

I am unable to understand the error received in read.WSdata, can anyone help, i tried all means mentioned above,

error is Error in data.frame(date = unique(WSdata$date), radiation_sum = tapply(WSdata$radiation, : arguments imply differing number of rows: 1, 0

[eelsaf]

Hi Guilhermo

I also have an error to import the weather data : Error in read.table(file = file, header = header, sep = sep, quote = quote, : 'file' must be a character string or connection

I've checked my csvfile as below

and I used this code :

MTLfile <- c("LC08_L1TP_126060_20191110_20191115_01_T1_MTL.txt") csvfile <- c('WSSiak2019.csv') c2 = read.csv(csvfile) m2 = read.delim(MTLfile) head(c2) head(m2) WS <- read.WSdata(WSdata = csvfile, date.format = "%d/%m/%Y", cf= c(1,1,1), lat=0.65222, long= 101.686389, elev=30, height= 2.2, columns=c("date" = 1, "time" = 2, "radiation" = 3, "wind" = 4, "RH" = 5, "temp" = 6, "rain" = 7), MTL = MTLfile)

Please, uploading the CSVfile into the WS function is always a trouble for me.

Thank you

[agronomofiorentini]

I have the same issue as @zaib19 and @eelsaf in order to run the read.WSdata function.

i will report here below the output of the console by using the str() function of the csv file used as an example by the water R package.

'data.frame':   96 obs. of  8 variables:
