hysplit_trajectory for February 2015

[noraini0210]

Hi

I am having difficulty with the hysplit trajectory and create_traj_model for February 2015.

library(SplitR)
library(lubridate)

trajectory <-
hysplit_trajectory(
traj_name = "traj",
lat = 6.0086,
lon = 102.4259,
height = 30,
duration = 120,
run_period = c("2015-02-01","2015-02-28"),
daily_hours = c(0, 6, 12, 18),
direction = "backward",
met_dir = "C:/GDAS/",
met_type = "gdas1",
exec_dir= "c:/hysplit4/working.559",
return_traj_df = TRUE)

Error in download.file(url, ...) :
cannot open URL 'ftp://arlftp.arlhq.noaa.gov/archives/gdas1/gdas1.feb15.w5'
In addition: Warning message:
In download.file(url, ...) : InternetOpenUrl failed: ''

I also try to use create_traj_model as suggested previously in August 2019 as followed:
traj_model <-
create_traj_model() %>%
add_grid(lat = 6.0086,lon = 102.4259,range = c(0.8, 0.8),division = c(0.2, 0.2)) %>%
add_params(
height = 30,
duration = 120,
run_period = c("2015-02-01","2015-02-28"),
daily_hours = c(0, 6, 12, 18),
direction = "backward",
met_type = "gdas1",
met_dir = "C:/GDAS/",
exec_dir = "c:/hysplit4/working.559"
) %>%
run_model()

However, I am still encountered the same error:
Error in download.file(url, ...) :
cannot open URL 'ftp://arlftp.arlhq.noaa.gov/archives/gdas1/gdas1.feb15.w5'
In addition: Warning message:
In download.file(url, ...) : InternetOpenUrl failed: ''

I have the same problem:

library(splitr)
library(magrittr)

trajectory <-

• hysplit_trajectory(

• lat = 40,
  

• lon = 13,
  

• height = 500,
  

• duration = 48,
  

• days = "2012-07-15",
  

• daily_hours = c(0,6,12,18),
  

• direction = "backward",
  

• met_type = "gdas1",
  

• extended_met = TRUE,
  

• traj_name = "prova",
  

• met_dir = "C:/gdas/", 
  

• clean_up = FALSE
  

• )
  trying URL 'ftp://arlftp.arlhq.noaa.gov/archives/gdas1/gdas1.lug12.w1'
  Error in download.file(url, ...) :

I've been unable to replicate the issue mentioned by @noraini0210 - code seems to run for the most recent code. (Is this code still unable to run for you @noraini0210?)

As for the example @maia2004 posted - this seems to be an issue with the locale argument of lubridate::month within the get_month_* functions? Since arlftp server has data months are all English, I suggest setting locale in lubridate::month to US as a fix.
